Use face milling cutters<\/span><\/h4>\n

\"fraises-a-surfacer\"<\/p>\n

Surface milling cutters are used to generate a planar surface perpendicular to the axis of rotation of the milling cutter.
\nThey are very well suited to surface a spoilboard<\/em><\/strong><\/span> and to correct defects of parallelism and flatness<\/span>.<\/p>\n

The size of the martyr plate must not be greater than the maximum working surface of the machine.

A) Indicate the dimensions of the spoilboard<\/span><\/strong><\/span><\/h4>\n

To do this, click on the folder \u00ab\u00a0machining<\/strong>\u00a0\u00bb and then choose the stock size<\/strong>
\nReminder :<\/strong><\/span> the size of the spoilboard<\/strong> in X and Y must correspond to the maximum move<\/strong> of the machine (working area)<\/p>\n

<\/p>\n

B) Draw the boundary of the area to be surfaced<\/span><\/strong><\/span><\/h4>\n

To do this, use the drawing icon (icons in green<\/span>) \u00ab\u00a0draw a rectangle<\/strong><\/span>\u00a0\u00bb<\/p>\n

<\/p>\n

Place the construction points of the rectangle at the bottom left and top right corners of the spoilboard<\/strong> in brown
\nWith this way the zone to be surfaced will correspond to the total surface of the martyr plate.<\/span><\/p>\n

<\/p>\n

C) Choose \u00ab\u00a0Pocket\u00a0\u00bb machining<\/span><\/span><\/h4>\n

A surfacing is the equivalent of machining an open pocket<\/span>
\n See the article on the strategy of machining the pockets to know the difference between closed pocket and open pocket<\/a>.<\/a><\/em><\/span><\/span><\/p>\n

To do this, select the rectangle previously draw<\/span> and click on the pocket icon<\/strong>.
\nA \u00ab\u00a0Pocket<\/strong>\u00a0\u00bb icon will appear under the machining folder<\/strong> and below \u00ab\u00a0Part1<\/strong>\u00ab\u00a0, click on it to set the machining.<\/span><\/p>\n

\"pocket-apparait-english-2\"<\/p>\n

D) Configuring pocket machining<\/span><\/strong><\/span><\/h4>\n

<\/p>\n

One surfacing pocket have theirs features :<\/strong><\/span>
\n– a very low machining depth<\/strong> because it is only necessary to eliminate the flatness defects or the traces of the previous machining operations.
\n– the tool must pass over a very large area<\/strong>.<\/p>\n

So, a relatively large tool diameter of 20 mm or more is used and a feed rate high enough to prevent the surfacing taking too long.<\/strong><\/span><\/p>\n

In this example :<\/strong><\/span>
\nThe tool have diameter of 20mm
\nFeed rate is high: 4000 mm \/ min
\nThe depth of machining is very low: 0.25mm<\/p>\n

The step over<\/strong> is 0.6 or 60%,  it’s a compromise between the surface quality and the time required for machining.<\/p>\n

For more information on the StepOver rate<\/span><\/a><\/span> see the article dedicated to the t<\/a>his subject<\/span><\/span><\/strong><\/p>\n

For the choice of machining direction, consult the dedicated article
\nConventional or climb milling direction<\/span><\/strong><\/span><\/a><\/p>\n

For region fill style you can leave the default setting \u00ab\u00a0Internal + Outside Offset<\/strong>\u00ab\u00a0.
\nIf you want another style, more information is available in
\n article on the strategy of machining the pockets<\/a><\/span><\/strong><\/em><\/p>\n

E) Creation of toolpaths and check of machining traces<\/span><\/span><\/h4>\n

<\/p>\n

After each change of machining parameter and before the creation of the Gcode you must generate the toolpaths
\nby right-clicking on the machining.<\/p>\n

\"view-show-cut-with\"<\/p>\n

\"step-over-too-big\"<\/p>\n

It is useful after generating the toolpaths to check the option \u00ab\u00a0Show Cut Width<\/strong>\u00a0\u00bb in the \u00ab\u00a0View<\/strong>\u00a0\u00bb menu
\nIn this example, you can see with 90% StepOver<\/strong>, there is some unmachined material<\/strong> in the middle and in the angles at the change of direction.
\nIt is necessary to reduce the StepOver rate<\/strong>, for example to 0.8 or 0.7, then regenerate the toolpaths and check the cutting widths<\/strong>.<\/p>\n

F) To ensure that the surfacing is carried out perfectly including around the plate<\/span><\/span><\/h4>\n

<\/p>\n

In the section \u00ab\u00a0Step Over<\/strong>\u00a0\u00bb
\nYou can indicate a negative value, so the tool will slightly overhang the surface.<\/p>\n

G) Creating the Gcode<\/span><\/span><\/h4>\n

<\/p>\n

The last step is to create the Gcode<\/span> by right clicking on the machining
\nThen \u00ab\u00a0Create gcode<\/strong>\u00a0\u00bb<\/p>\n

You can give a name to your Gcode file before the extension \u00ab\u00a0nc<\/strong>\u00a0\u00bb and save it in the \u00ab\u00a0Gcode\u00a0\u00bb folder of the SD card<\/strong> of your smoothiebox.<\/p>\n

Also save your CAMBAM file on your computer by doing \u00ab\u00a0File —> save as<\/strong>\u00ab\u00a0, this will be useful for your future spoilboard, especially if you want to change some settings without having to do it again.<\/p>\n

 A ) Modeling spoilboard<\/span><\/span><\/strong><\/h4>\n

In Fusion 360 can modeling directly in 3D before machining.<\/p>\n

The spoilboard is a parallelepiped, so start modeling a parallelepipedic volume.
\nYou can follow there links below, it’s lesson in chinese<\/p>\n

– Pr\u00e9sentation of fusion 360<\/a> software<\/strong><\/span>
\n– Install fusion 360<\/strong><\/span><\/a>
\n– Cr\u00e9ation of parall\u00e9l\u00e9pip\u00e8de with Fusion 360<\/strong><\/span><\/a><\/p>\n

To know more about use Fusion 360 can see the youtube chanel of Taiwan designer Channelbox MAYA<\/a>
\nhttps:\/\/www.youtube.com\/watch?v=BAHkGNsh4iE&list=PLZJ2lSlFhOX0x71u1YVgUFaWuet_Cf2aF<\/strong><\/span><\/a><\/p>\n

B) Possibly give an appearance to spoilboard<\/span><\/span><\/strong><\/h4>\n

\"surfacage-fusion-1\"<\/p>\n

\"surfacage-fusion-2\"<\/p>\n

For more realism you can choose an appearance, for example pine wood or MDF..<\/span>
\nFor this you have to right click<\/strong> when the mouse pointer is on the plate and choose \u00ab\u00a0Appearance<\/strong>\u00a0\u00bb<\/p>\n

C) Switch from the modeling module to the machining preparation module<\/span><\/span><\/h4>\n

\"surfacage-fusion-3\"<\/p>\n

D) Start a machining configuration<\/span><\/span><\/h4>\n

\"create-setup-fusion-360\"<\/p>\n

To do this, you must select \u00ab\u00a0Setup<\/strong>\u00a0\u00bb and then \u00ab\u00a0New Setup<\/strong>\u00a0\u00bb<\/p>\n

\"browser-setup\"<\/h4>\n

A folder setup<\/strong> will be created in the \u00ab\u00a0Browser<\/strong>\u00a0\u00bb that it is placed under the history of modeling.
\nBy right-clicking on the setup created<\/strong> it is possible to remodify<\/strong> each configuration parameter<\/span><\/p>\n

E) Select the point of origin and orientation of the work coordinate system<\/span><\/span><\/strong><\/h4>\n

\"surfacage-fusion-5\"<\/p>\n

To conform to the origin point set in the Formosa CNC, choose an origin at the top left corner.<\/p>\n

\"surfacage-fusion-6\"<\/p>\n

 <\/p>\n

The Z axis is misaligned<\/strong> to match the architecture of the machine it would have to be vertical.<\/p>\n

So go the \u00ab\u00a0Model orientation<\/strong>\u00a0\u00bb of the WCS<\/strong> and choose a selection of the Z and X axes.<\/p>\n

 <\/p>\n

\"flip-z-axis\"<\/p>\n

If one of the axes has a wrong direction it is possible to check the box \u00ab\u00a0Flip<\/strong>\u00a0\u00bb<\/p>\n

Note :<\/strong><\/span><\/span><\/h4>\n

If you want to directly have the WCS properly oriented when you switch into the CAM module, it is necessary to do the design thinking about the machine.<\/p>\n

For exemple<\/span>, design first sketch in XY plane and extrude along Z axis.
\nBecause the spindle move along the Z axis.
\n\"select-face-to-drawing\"<\/p>\n

\"parametrage-stock-3\"<\/p>\n

The case of sploilboard surfacing is  particular because the dimensions of the sploilboard are the same as those of the final part in X and Y.<\/p>\n

For the Z dimension a very small part of material will be removed like 0.25mm<\/p>\n

It is therefore necessary to set \u00ab\u00a00\u00a0\u00bb to all offset except 0.25mm for \u00ab\u00a0Stock Top Offset.<\/span>
\nThe spoilboard will be of the same size as the finished object machined for X and Y and only 0,25mm will be removed during the surfacing operation.<\/p>\n

G) Add the surface machining operation<\/span><\/span><\/h4>\n

\"choix-operation-surfacage\"<\/p>\n

Choice of tool<\/strong><\/span><\/h5>\n

Choose the tool according to the type of operation (mark 2<\/span>), and choose Face (Mark 3<\/span>)<\/strong><\/p>\n

\"choix-outil-1\"<\/p>\n

 <\/p>\n

\"edit-mill-tool\"<\/p>\n

 <\/p>\n

You can filter by diameter for example 20mm<\/strong>
\nThen choose from the list a cutter for plastic or wood with flat end.<\/p>\n

And then to fit your tool right click \u00ab\u00a0Edit Tool<\/strong>\u00a0\u00bb<\/p>\n

 <\/p>\n

\"edit-cutter-tool\"\"edit-feedrate\"<\/p>\n

You can modify some parameters such as the number of teeth of the tool<\/strong> and the feed rate<\/strong>.
\nFor other parameters if you do not have a spindle drive, if you do not have an ATC system with an automatic tool magazine, it is not worth changing them.
\nThe Formosa CNCs are designed to be as simple to use as possible and there is no MCS<\/strong> (m<\/strong>achine c<\/strong>oordinate s<\/strong>ystem) or tool offset recording<\/strong> as for machines used in the industry.<\/p>\n

Setting an offset around the surface to be machined<\/strong><\/span><\/h5>\n

To be sure that the outer limit of spoilboard will bee surfaced you can add an offset (offset)
\nTo do this, go to the \u00ab\u00a0Passes<\/strong>\u00a0\u00bb tab and then enter a value in the \u00ab\u00a0Stock Offset<\/strong>\u00a0\u00bb part (2 mm in the example below)<\/p>\n

\"fusion-360-stock-offset\"<\/p>\n

\nWith this way the zone to be surfaced will correspond to the total surface of the martyr plate.<\/span><\/p>\n

<\/p>\n

C) Choose \u00ab\u00a0Pocket\u00a0\u00bb machining<\/span><\/span><\/h4>\n

A surfacing is the equivalent of machining an open pocket<\/span>
\n See the article on the strategy of machining the pockets to know the difference between closed pocket and open pocket<\/a>.<\/a><\/em><\/span><\/span><\/p>\n

To do this, select the rectangle previously draw<\/span> and click on the pocket icon<\/strong>.
\nA \u00ab\u00a0Pocket<\/strong>\u00a0\u00bb icon will appear under the machining folder<\/strong> and below \u00ab\u00a0Part1<\/strong>\u00ab\u00a0, click on it to set the machining.<\/span><\/p>\n

D) Configuring pocket machining<\/span><\/strong><\/span><\/h4>\n

<\/p>\n

One surfacing pocket have theirs features :<\/strong><\/span>
\n– a very low machining depth<\/strong> because it is only necessary to eliminate the flatness defects or the traces of the previous machining operations.
\n– the tool must pass over a very large area<\/strong>.<\/p>\n

So, a relatively large tool diameter of 20 mm or more is used and a feed rate high enough to prevent the surfacing taking too long.<\/strong><\/span><\/p>\n

In this example :<\/strong><\/span>
\nThe tool have diameter of 20mm
\nFeed rate is high: 4000 mm \/ min
\nThe depth of machining is very low: 0.25mm<\/p>\n

The step over<\/strong> is 0.6 or 60%,  it’s a compromise between the surface quality and the time required for machining.<\/p>\n

For more information on the StepOver rate<\/span><\/a><\/span> see the article dedicated to the t<\/a>his subject<\/span><\/span><\/strong><\/p>\n

For the choice of machining direction, consult the dedicated article
\nConventional or climb milling direction<\/span><\/strong><\/span><\/a><\/p>\n

For region fill style you can leave the default setting \u00ab\u00a0Internal + Outside Offset<\/strong>\u00ab\u00a0.
\nIf you want another style, more information is available in
\n article on the strategy of machining the pockets<\/a><\/span><\/strong><\/em><\/p>\n

E) Creation of toolpaths and check of machining traces<\/span><\/span><\/h4>\n

<\/p>\n

After each change of machining parameter and before the creation of the Gcode you must generate the toolpaths
\nby right-clicking on the machining.<\/p>\n

\"view-show-cut-with\"<\/p>\n

\"step-over-too-big\"<\/p>\n

It is useful after generating the toolpaths to check the option \u00ab\u00a0Show Cut Width<\/strong>\u00a0\u00bb in the \u00ab\u00a0View<\/strong>\u00a0\u00bb menu
\nIn this example, you can see with 90% StepOver<\/strong>, there is some unmachined material<\/strong> in the middle and in the angles at the change of direction.
\nIt is necessary to reduce the StepOver rate<\/strong>, for example to 0.8 or 0.7, then regenerate the toolpaths and check the cutting widths<\/strong>.<\/p>\n

F) To ensure that the surfacing is carried out perfectly including around the plate<\/span><\/span><\/h4>\n

<\/p>\n

In the section \u00ab\u00a0Step Over<\/strong>\u00a0\u00bb
\nYou can indicate a negative value, so the tool will slightly overhang the surface.<\/p>\n

G) Creating the Gcode<\/span><\/span><\/h4>\n

<\/p>\n

The last step is to create the Gcode<\/span> by right clicking on the machining
\nThen \u00ab\u00a0Create gcode<\/strong>\u00a0\u00bb<\/p>\n

You can give a name to your Gcode file before the extension \u00ab\u00a0nc<\/strong>\u00a0\u00bb and save it in the \u00ab\u00a0Gcode\u00a0\u00bb folder of the SD card<\/strong> of your smoothiebox.<\/p>\n

Also save your CAMBAM file on your computer by doing \u00ab\u00a0File —> save as<\/strong>\u00ab\u00a0, this will be useful for your future spoilboard, especially if you want to change some settings without having to do it again.<\/p>\n

 A ) Modeling spoilboard<\/span><\/span><\/strong><\/h4>\n

In Fusion 360 can modeling directly in 3D before machining.<\/p>\n

The spoilboard is a parallelepiped, so start modeling a parallelepipedic volume.
\nYou can follow there links below, it’s lesson in chinese<\/p>\n

– Pr\u00e9sentation of fusion 360<\/a> software<\/strong><\/span>
\n– Install fusion 360<\/strong><\/span><\/a>
\n– Cr\u00e9ation of parall\u00e9l\u00e9pip\u00e8de with Fusion 360<\/strong><\/span><\/a><\/p>\n

To know more about use Fusion 360 can see the youtube chanel of Taiwan designer Channelbox MAYA<\/a>
\nhttps:\/\/www.youtube.com\/watch?v=BAHkGNsh4iE&list=PLZJ2lSlFhOX0x71u1YVgUFaWuet_Cf2aF<\/strong><\/span><\/a><\/p>\n

B) Possibly give an appearance to spoilboard<\/span><\/span><\/strong><\/h4>\n

\"surfacage-fusion-1\"<\/p>\n

\"surfacage-fusion-2\"<\/p>\n

For more realism you can choose an appearance, for example pine wood or MDF..<\/span>
\nFor this you have to right click<\/strong> when the mouse pointer is on the plate and choose \u00ab\u00a0Appearance<\/strong>\u00a0\u00bb<\/p>\n

C) Switch from the modeling module to the machining preparation module<\/span><\/span><\/h4>\n

\"surfacage-fusion-3\"<\/p>\n

D) Start a machining configuration<\/span><\/span><\/h4>\n

\"create-setup-fusion-360\"<\/p>\n

To do this, you must select \u00ab\u00a0Setup<\/strong>\u00a0\u00bb and then \u00ab\u00a0New Setup<\/strong>\u00a0\u00bb<\/p>\n

\"browser-setup\"<\/h4>\n

A folder setup<\/strong> will be created in the \u00ab\u00a0Browser<\/strong>\u00a0\u00bb that it is placed under the history of modeling.
\nBy right-clicking on the setup created<\/strong> it is possible to remodify<\/strong> each configuration parameter<\/span><\/p>\n

E) Select the point of origin and orientation of the work coordinate system<\/span><\/span><\/strong><\/h4>\n

\"surfacage-fusion-5\"<\/p>\n

To conform to the origin point set in the Formosa CNC, choose an origin at the top left corner.<\/p>\n

\"surfacage-fusion-6\"<\/p>\n

 <\/p>\n

The Z axis is misaligned<\/strong> to match the architecture of the machine it would have to be vertical.<\/p>\n

So go the \u00ab\u00a0Model orientation<\/strong>\u00a0\u00bb of the WCS<\/strong> and choose a selection of the Z and X axes.<\/p>\n

 <\/p>\n

\"flip-z-axis\"<\/p>\n

If one of the axes has a wrong direction it is possible to check the box \u00ab\u00a0Flip<\/strong>\u00a0\u00bb<\/p>\n

Note :<\/strong><\/span><\/span><\/h4>\n

If you want to directly have the WCS properly oriented when you switch into the CAM module, it is necessary to do the design thinking about the machine.<\/p>\n

For exemple<\/span>, design first sketch in XY plane and extrude along Z axis.
\nBecause the spindle move along the Z axis.
\n\"select-face-to-drawing\"<\/p>\n

\"parametrage-stock-3\"<\/p>\n

The case of sploilboard surfacing is  particular because the dimensions of the sploilboard are the same as those of the final part in X and Y.<\/p>\n

For the Z dimension a very small part of material will be removed like 0.25mm<\/p>\n

It is therefore necessary to set \u00ab\u00a00\u00a0\u00bb to all offset except 0.25mm for \u00ab\u00a0Stock Top Offset.<\/span>
\nThe spoilboard will be of the same size as the finished object machined for X and Y and only 0,25mm will be removed during the surfacing operation.<\/p>\n

G) Add the surface machining operation<\/span><\/span><\/h4>\n

\"choix-operation-surfacage\"<\/p>\n

Choice of tool<\/strong><\/span><\/h5>\n

Choose the tool according to the type of operation (mark 2<\/span>), and choose Face (Mark 3<\/span>)<\/strong><\/p>\n

\"choix-outil-1\"<\/p>\n

 <\/p>\n

\"edit-mill-tool\"<\/p>\n

 <\/p>\n

You can filter by diameter for example 20mm<\/strong>
\nThen choose from the list a cutter for plastic or wood with flat end.<\/p>\n

And then to fit your tool right click \u00ab\u00a0Edit Tool<\/strong>\u00a0\u00bb<\/p>\n

 <\/p>\n

\"edit-cutter-tool\"\"edit-feedrate\"<\/p>\n

You can modify some parameters such as the number of teeth of the tool<\/strong> and the feed rate<\/strong>.
\nFor other parameters if you do not have a spindle drive, if you do not have an ATC system with an automatic tool magazine, it is not worth changing them.
\nThe Formosa CNCs are designed to be as simple to use as possible and there is no MCS<\/strong> (m<\/strong>achine c<\/strong>oordinate s<\/strong>ystem) or tool offset recording<\/strong> as for machines used in the industry.<\/p>\n

Setting an offset around the surface to be machined<\/strong><\/span><\/h5>\n

To be sure that the outer limit of spoilboard will bee surfaced you can add an offset (offset)
\nTo do this, go to the \u00ab\u00a0Passes<\/strong>\u00a0\u00bb tab and then enter a value in the \u00ab\u00a0Stock Offset<\/strong>\u00a0\u00bb part (2 mm in the example below)<\/p>\n

Une poche de surfa\u00e7age \u00e0 comme caract\u00e9ristiques :
\n– une profondeur d’usinage tr\u00e8s faible<\/strong> car il s’agit seulement d’\u00e9liminer les d\u00e9fauts de plan\u00e9it\u00e9 ou les traces des usinages pr\u00e9c\u00e9dent.
\n– d’outil doit passer sur une tr\u00e8s grande surface.<\/strong><\/p>\n

Donc on utilise un diam\u00e8tre d’outil assez important, \u00e9gal ou sup\u00e9rieur \u00e0 20mm et une vitesse d’avance assez \u00e9lev\u00e9 pour \u00e9viter que le surfa\u00e7age\u00a0prenne trop de temps.<\/span><\/p>\n

Dans la partie \u00ab\u00a0Contr\u00f4le des d\u00e9placements lat\u00e9raux<\/strong>\u00a0\u00bb
\nvous pouvez indiquer une sur\u00e9paisseur n\u00e9gative, ainsi la fraise va d\u00e9border l\u00e9g\u00e8rement de plaque pour surfacer.<\/p>\n

\npuis \u00ab\u00a0Cr\u00e9er le gcode<\/strong>\u00a0\u00bb<\/p>\n

Vous pouvez donner un nom \u00e0 votre fichier Gcode qui se termine par l’extension \u00ab\u00a0nc\u00a0\u00bb et l’enregistrer dans le dossier \u00ab\u00a0Gcode\u00a0\u00bb de la SD-Card de votre\u00a0smoothiebox.<\/p>\n

Enregistrez aussi votre fichier CAMBAM sur votre ordinateur en faisant \u00ab\u00a0Fichier —> enregistrer sous<\/strong>\u00ab\u00a0, cela vous sera utile lors de vos prochains surfa\u00e7ages de martyr surtout si vous voulez changer quelques param\u00e9trages sans \u00eatre oblig\u00e9 de tout refaire.<\/p>\n

\u00a0A ) Mod\u00e9lisation de la plaque martyr<\/span><\/span><\/h3>\n

Nous allons afin de s\u2019entra\u00eener pour des usinages plus complexe, pr\u00e9parer le surfa\u00e7age \u00e0 partir d’un mod\u00e8le 3D<\/p>\n

Vous allez donc mod\u00e9liser au pr\u00e9alable la plaque martyr qui est un simple parall\u00e9l\u00e9pid\u00e8de et suivre les indications des articles
\n– Pr\u00e9sentation du logiciel fusion 360<\/strong><\/span><\/a> \u00a0 \u00e9ventuellement \u00a0\u00a0Utiliser Fusion 360 lorsqu’il n’y a plus internet<\/strong><\/span><\/a>

B\u00a0) Eventuellement donnez une apparence \u00e0 la plaque martyr<\/span><\/span><\/h4>\n

\"surfacage-fusion-1\"<\/p>\n

\"surfacage-fusion-2\"<\/p>\n

Pour plus de r\u00e9alisme vous pouvez choisir une apparence, par exemple du pin (Pine en Anglais) ou du MDF.
\nPour cela il faut faire un clic droit lorsque le pointeur de souris est sur la plaque et choisir \u00ab\u00a0Appearance<\/strong>\u00a0\u00bb<\/p>\n

C ) Basculez du module mod\u00e9lisation \u00e0 celui de pr\u00e9paration d’usinage<\/span><\/span><\/h4>\n

\"surfacage-fusion-3\"<\/p>\n

D\u00a0) D\u00e9marrez une configuration d’usinage<\/span><\/span><\/h4>\n

\"create-setup-fusion-360\"<\/p>\n

Pour cela il faut dans \u00ab\u00a0Setup<\/strong>\u00a0\u00bb puis \u00ab\u00a0New Setup<\/strong>\u00a0\u00bb<\/p>\n

\"browser-setup\"<\/h4>\n

Un dossier setup se cr\u00e9er dans le \u00ab\u00a0Browser\u00a0\u00bb celui ci se met en dessous de l’historique de mod\u00e9lisation.
\nEn faisant un clic droit sur le setup ainsi cr\u00e9er il est possible de remodifier chaque param\u00e8tre de configuration<\/p>\n

E\u00a0) Choisir le point d’origine et l’orientation du syst\u00e8me de coordonn\u00e9e de travail<\/span><\/span><\/h4>\n

\"surfacage-fusion-5\"<\/p>\n

Pour que cela soit conforme au point d’origine param\u00e9tr\u00e9 dans la CNC Formosa, il faut choisir une origine au coin sup\u00e9rieur avant gauche.<\/p>\n

\"surfacage-fusion-6\"<\/p>\n

 <\/p>\n

L’axe Z est mal orient\u00e9 pour correspondre \u00e0 l’architecture de la machine il faudrait qu’il soit vertical.<\/p>\n

Allez donc le \u00ab\u00a0Model orientation\u00a0\u00bb du WCS et choisissez une s\u00e9lection de l’axe Z et X.<\/p>\n

 <\/p>\n

\"flip-z-axis\"<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Si un des axe a une mauvaise direction il est possible de cocher la case \u00ab\u00a0Flip\u00a0\u00bb
\nDans l’exemple si contre le sens positif de l’axe Z \u00e9tait vers le bas.
\nAvec l’option \u00ab\u00a0Flip Z axis\u00a0\u00bb coch\u00e9 il pointe maintenant vers le haut.<\/p>\n

 <\/p>\n

Remarque :<\/strong><\/span><\/span><\/h4>\n

Si vous voulez avoir\u00a0directement le WCS correctement orient\u00e9 quand vous basculez dans le module CAM, il est n\u00e9cessaire de faire la conception en pensant \u00e0 la machine qui va r\u00e9aliser votre pi\u00e8ce.\u00a0\"select-face-to-drawing\"<\/p>\n

F\u00a0) Param\u00e9trer le brut<\/span><\/span><\/h4>\n

\"parametrage-stock-3\"<\/p>\n

Le cas du surfa\u00e7age de plaque martyr est un peu particulier car les dimensions du brut sont les m\u00eames que celles de\u00a0la pi\u00e8ce finale en X et Y.<\/p>\n

Pour la dimension en Z tr\u00e8s peu de mati\u00e8re sera enlev\u00e9e par exemple 0,25mm<\/p>\n

Il faut donc mettre \u00ab\u00a00\u00a0\u00bb \u00e0 tous les offset\u00a0sauf 0,25mm pour \u00ab\u00a0Stock Top Offset.<\/strong>
\nAinsi le brut sera de la m\u00eame dimension que l’objet final usin\u00e9 pour X et Y et seulement 0,25mm sera enlev\u00e9 lors de l’op\u00e9ration de surfa\u00e7age.<\/p>\n

 <\/p>\n

G\u00a0) Ajouter l’op\u00e9ration d’usinage surfa\u00e7age<\/span><\/span><\/h4>\n

\"choix-operation-surfacage\"<\/p>\n

Choix de l’outil<\/span><\/strong><\/p>\n

\"choix-outil-1\"<\/p>\n

Choisir l’outil en fonction du type\u00a0d’op\u00e9ration ( Rep\u00e8re 2 )<\/strong> et choisir Face ( Rep\u00e8re 3 )<\/strong><\/p>\n

\"edit-mill-tool\"<\/p>\n

 <\/p>\n

Vous pouvez filtrer par diam\u00e8tre par exemple 20mm
\nEnsuite choisir dans la liste une fraise pour plastique ou bois \u00e0 embout plat.<\/p>\n

Et ensuite pour adapter \u00e0 votre outil faire clic droit \u00ab\u00a0Edit Tool<\/strong>\u00a0\u00bb<\/p>\n

 <\/p>\n

\"edit-cutter-tool\"\"edit-feedrate\"<\/p>\n

Vous pouvez modifier quelques param\u00e8tres comme par exemple le nombre de dent de l’outil et la vitesse d’avance.
\nPour les autres param\u00e8tres si vous n’avez pas de de variateur de broche, si vous n’avez pas de syst\u00e8me ATC avec magasin d’outil automatique, cela n’a pas d\u2019int\u00e9r\u00eat de les changer.
\nLes CNC Formosa sont con\u00e7u pour \u00eatre les plus simple possible \u00e0 utiliser et il n’y a pas de syst\u00e8me MCS ( rep\u00e8re de coordonn\u00e9e machine ) ni d’enregistrement de d\u00e9calage d’outil comme pour les machines utilis\u00e9es dans l’industrie.<\/p>\n

Param\u00e9trage d’un d\u00e9calage autour de la surface \u00e0 usiner<\/span><\/strong><\/p>\n

Pour \u00eatre sur que le tour de la plaque martyr soit surfacer vous pouvez ajoutez un d\u00e9calage ( offset )
\nIl faut pour cela aller dans l’onglet \u00ab\u00a0Passes\u00a0\u00bb et ensuite entrer une valeur dans la partie \u00ab\u00a0Stock Offset\u00a0\u00bb ( 2 mm dans l’exemple ci-dessous )<\/p>\n
