3D Parallel Finishing

3D Parallel Finishing is used when machining 3D parts, to produce the final shape of the part in the stock.

3D Parallel Finishing requires a single surface or polysurface to machine. You will need to place this surface into the following layer in the Rhino document:

KaroroCAM/3D Finishing

NOTE: Currently KaroroCAM can only process one surface/polysurface at a time - you will see a warning if you have 2 or more surfaces in the above layer.

Tolerance

KaroroCAM uses polylines (collections of line segments) to create toolpaths. All curves are converted to segments using this Tolerance setting as a guide. The Number represents the maximum deviation from the input curve to the final polyline.

Pass Angle

This sets the angle (relative to the X axis) of the 3D Parallel finishing passes.

Tool

Tool Shape

3D Parallel Finishing uses Ball End Mill tools:

Tool Diameter

Sets the diameter of your tool bit in mm.

Tool Number

Select Tool number that matches the tool spec'd in your tool path - mostly important for machines with auto tool change ability.

Spindle Speed

Sets the spindle speed for this operation in your GCode output file

Step Over

Step Over

Sets the step over between offset passes in the 3D Parallel Finishing

TIP: For best surface finishes use a step over of 33% of your tool diameter or less

Tool Containment

This menu give you three options to contain the 3D Roughing toolpath on the side of model surface:

Path Linking

Path Linking

Check this box to use Path Linking - tool bit will move directly from the end of one parallel pass to the start of the next without a Z movement to the safe height.

Max Link Distance % of Step Over

Gives that maximum distance between parallel paths that the tool bit will stay down. 

EXAMPLE: If the step over is 10mm and the Max Link Distance % is 200% the longest gap between parallel paths that will be linked directly is 20mm.
