The RhinoCAM Project
The Machining Setup
The Part Geometry
Stock from Selection
To save machining time Max has modeled his stock to match the actual stock that the parts will be cut from. In image (C) below you see the 3D stock models displayed. With the stock models selected in Rhino, you simply select “Stock from Selection” from the RhinoCAM Stock menu. This assigns the selected geometry as the current stock definition. After this is done, you then hide the actual stock geometry by turning off that layer in Rhino. In the image (D) you see that the stock definition matches the shape of the stock geometry.
Stock from Selection is a feature that is available starting with the Professional configuration of RhinoCAM. It is used anytime you have an irregular stock definition. For example, it can be used when the stock needs to match a casted blank. It can also be used anytime you want to minimize machining to a specific shape. IMPORTANT: Make sure you hide the actual stock geometry after defining the Stock from Selection! |
3 Axis Curve Machining
After using 3 Axis Horizontal Roughing and the Re-Roughing, the finishing operation in this setup is a 3 Axis Curve Machining strategy using a ¾” ball mill cutter. Curve Machining is another advanced 3 Axis strategy available in the RhinoCAM Professional configuration. In this operation the toolpath is offset from a drive curve and projected downward onto the underlying part surface. A cutting band width of 3.5” and a stepover distance of 0.112” (15%) matches the part width. The operation also uses straight cut connections between stepovers. The images below illustrate the operation. Note that the selected drive curves are at the top outer edges of the part.
