Mastercam v9 surface toolpath tutorial series#

To verify the piece is in the correct position hit F9 on the keyboard, the axis will appear. If the distance is correct then your piece imported with the proper scale, if not, you will need to scale your piece in MasterCAM before you begin the tool-path.ДЈ) Once you have verified the scale you can change the view to a 3D view by clicking on the GView Isometric button (the twelfth button from the left in the top row). Click with the mouse on two points on the piece, the distance be-tween those points will be displayed in the dialog area at the bottom of the screen. From Analyze choose Between Pts and Sketch. To measure the piece, select Analyze from the main menu. To verify the scale measure the overall dimension of the piece, or a know dimension of a portion of the piece. Once you can see your entire model in plan it is a good idea to verify that it imported with the correct scale and in the correct position. Your model should now appear in plan view.Дў) Zoom out to view the entire model by clicking the Screen Fit button (the ninth button from the left at the top of the interface). You will be prompted to Delete Current Part, unless you are importing your file into an existing MasterCAM model, click OK. A second dialog box with IGES Read Parameters will appear, leave all the settings as they are and click OK. To import your new file in the MasterCAM select File -> Convert-ers -> IGES -> Read File, a file dialog box should appear. If possible it is suggested you select the individual elements to be CNC milled and export only those pieces, avoiding the exporting of lights, cameras, other objects, etc.ДЄvery Fabrication and Material Conservation LaboratoryДЎ) Once you have an IGES file you can quit your 3D model-ing application and open MasterCAM Mill. The part should also be positioned entirely in the positive XY quadrant (upper right quadrant) of the axisДў) Once you have modeled a surface it must be exported as a file in IGES format. The mill will treat the XY plane as the top of the material, anything above the XY plane will not be cut. The surface should be placed with the highest point on the surface is just below the XY plane. The optimal surface for machining is NURBS based, this can be created in Maya, Rhino or 3DMax. As you prepare your surface the modeling environment should be set so the Z-axis is vertical and the working units are inches/feet. This tutorial covers the basic opera-tions needed to do a Rough tool path based on a generic 3D surface.ДЎ) The creation of an appropriate surface for machining is the first step in the Surfacing operation.

If a smoother finished surface is desirable a second series of cuts can be made with a smaller bit at a tighter interval giving a smooth polished surface. Often the process is stopped after the Rough process, and if the roughing operation is done with a small enough bit the surface smoothness may be suitable for many applications. The purpose of the Rough pass is to remove as much material in as quick of time as possible, this is typically done with a large bit and gives a rough couduroy texture to the material. Typically this is done in two operations, a Rough pass and a Finish pass. Surfacing is a machining operation in which a 3D contoured surface is carved from a block of stock material through a series of cuts.
