Cut Parameters tab, Between 2 Curves Machining, 3 Axis

The following Cut Parameters tab allows you to define the cut parameters for the current 3 Axis Between 2 Curves Machining operation.  You can set Global Parameters, Cut Pattern, Cut Direction and Stepover Control via this tab of the operation dialog.  The Global Parameters section allows you to set the tolerance value to be used in machining.  A uniform thickness or stock that needs to be left around the part can also be specified here.  Refer to each option below.

Global Parameters, 3 Axis Operations

The Global Parameters section allows you to set the tolerance value to be used in machining. Intol and Outol are allowable deviations (tolerances) from the actual part geometry plus the Stock layer (if any).  A uniform thickness or stock that needs to be left around the part can be specified here.

Intol / Outol
Inward tolerance - the maximum thickness of material that can be removed from the Stock layer.  Outward tolerance is the maximum thickness of material that can remain above the Stock layer.

 

How to Increase Tool Path AccuracyTolerances play a vital role in both design engineering and digital manufacturing.  In design, the goal is to allow the broadest tolerance range possible while meeting your design specifications. This is because, generally speaking, there is a direct correlation between tighter tolerances and higher manufacturing costs.

Stock  
The thickness of the layer that will remain on top of the part after the toolpath is complete. Roughing operations generally leave a thin layer of stock, but for finishing operations this value is zero.
tog_minusCut Direction

This can be specified as Along or Across.

Cut Direction = Along

Along
Cut Direction = Across

Across
tog_minusCut Pattern

This allows you to define the type of cut pattern that the tool will follow. The two types of cut patterns that are available are ZigZag and Zig. In the ZigZag cut pattern, the cutter traverses back and from along the cuts. In the Zig cut pattern the cutter traverses the cuts in a single direction.

Cut Pattern = Zig

Zig
Cut Pattern = ZigZag

tog_minusStepover Control
Stepover Control, 3 Axis Operations

Stepover Control, 3 Axis Operations

This allows you to define the spacing between the cuts.  Select from the following options:

% Tool Diameter  
Enter the stepover distance as a percentage value of the tool diameter.

Distance  
Enter the exact stepover distance preferred.

Scallop

(not available for all operations)
Enter the scallop height to determine the spacing between cuts.
