Check that geometry fits within the maximum machinable extents of the intended CNC mill. Organize geometry in Rhino by layer, such that each layer will receive similar treatment in MasterCAM e. Building Tops, Draped Surface, etc. Click file in the ribbon menu, and choose merge to open the file picker window.

Select the. Click open , and the geometry appears in the MasterCAM model space. Select and then de-select an option from the bottom "Settings' of the Merge Dialog. This slowdown can be avoided by changing Visibility from shaded to wireframe prior to merging. Because the origin of the file typically corresponds to the origin used on the machine, it is important that your geometry be located relative to the origin such that it is appropriately located on the machine.

Working far from the World Top Plane Origin in Rhino or similar applications will often cause the geometry to be located far from the origin in MasterCAM, so it's best to catch this issue early, before getting too far along in MasterCAM. Your geometry should be located within the positive X, Y, and Z quadrants, with the stock modeled such that it has a corner located at 0,0,0.

The gnomon and axes visible on the screen should help to verify whether the geometry needs to move in order to satisfy this condition. Machine dimensions vary, as do the lengths of their respective axes of travel. Make sure your geometry fits within the dimensions of the machine you intend to use.

MasterCAM will use the input stock size when simulating, so it is vital to ensure that dimensions are true to the physical material that will be placed on the milling table. In the toolpath manager pane, expand the properties subgroup. Choose stock setup , and the machine group properties window opens.

The stock box is represented by a dashed red rectangular prism. Enter the as-measured dimensions of your stock into the X, Y, Z fields. Default units are inches. Tick the display checkbox to show stock box in MasterCAM model space. After defining stock dimensions, u sers MUST manually update machining heights to reflect the stock thickness for each operation individually.

MasterCAM will not auto-update these values. Inaccurate values cause collisions during verification. A roughing operation is used to remove large amounts of material rapidly and to produce a part geometry close to the desired shape. A roughing operation uses large diameter tools and coarse settings, and should not cut all the way down to the drive surface s , instead leaving a small offset for the finishing operations to clean up afterwards.

When stock thickness exceeds the shoulder length of the tools, the surrounding uncut stock may interfere with toolpaths drawn on the perimeter of the part, causing collisions. In this circumstance, it is necessary to partially clear away the stock outside the part perimeter before proceeding to the finishing operations. The Contour 2D operation may be used for roughing as follows:.

Note that the Contour 2D operation is not context-aware. Nearby parts may be gouged if there are multiple parts being machined from a single stock. The Surface Rough Parallel operation moves the tool in equally spaced parallel passes in the XY plane across the surface, cutting down incrementally in multiple steps. The toolpath can be drawn as One Way best for anisotropic materials with grain direction, slower or Zigzag best for isotropic materials, faster. Note that all surfaces except stock extents are assigned as Drive surfaces in a typical MasterCAM file.

A finishing operation follows roughing and is used to achieve the final geometry and surface finish. Most MasterCAM files need at least one and frequently several separate finishing operations to produce an acceptable part.

Finishing operations clean up the extra material purposefully left behind by the roughing operation. Finishing operations must be employed on a case-by-case basis, as the utility of each operation type varies from one file and geometry to the next.

See reference pages linked above for a detailed explanation of concepts and usage that are common across all operation types. Commonly used finishing operations are listed below. Users must review them and determine which operations are appropriate for their geometry. The Surface Finish Parallel operation moves the tool in equally spaced parallel passes in the XY plane across the surface. The toolpath can be drawn in any angle relative to the XY origin.

This operation is often used with varying stepovers and machining angles to create surface patterns on site models.

Used primarily to clear material from vertical or steep features. The Surface Finish Contour operation cuts geometry by offsetting toolpaths away from the drive surface at incremental heights. As sloped geometry becomes steeper, the toolpaths get closer together; as that Wood Word Cutting Machine Gun geometry becomes more shallow, the toolpaths are spaced farther apart.

This operation is often paired with a flat endmill for use on vertical building faces. Note that the horizontal surface building top is the Drive surface. Used primarily to clear flat areas, such as stepped terrain or building tops. The Surface Finish Shallow operation cuts geometry whose slope angle does Wood Word Cutting Machine 2021 not exceed a threshold users can set maximum. This operation is often paired with a flat endmill for use on stepped topography and building tops.

Users can dramatically reduce machining time by strategically using larger diameter tools to cut open areas, while targeting small diameter tools to narrower channels. Used primarily to clear sloped areas, such as rolling topography.

The Surface Finish Constant Scallop operation cuts geometry by dynamically adjusting stepover users can set maximum as a function of the slope angle for any given point along the drive surface. This method maintains a uniform scallop height across variable relief, and thus uniform smoothness. This operation is often paired Wood Word Cutting Machine Repair with a ball endmill for use on rolling topography and gentle slopes.

Used to cut flat-bottomed holes, such as building footprints. The Pocket operation removes material from within a closed chain, creating recesses with flat bottoms.

Note that t he Pocket operation includes its own internal Roughing and Finishing stages within the parameters. This operation is often paired with a flat endmill to cut building footprints. Pockets are preferred over Surface Finish Shallow for cutting deep, flat-bottomed recesses due to their incorporation of incremental depth cuts.

Used to trace linear features, such as final perimeter cut-out. The Contour operation cuts along a chain or series of chains. The cut may be compensated to the left or right of the chain s , or on center if compensation is turned off. Employability skills. Elements describe the essential outcomes of a unit of competency.
