3+2 Roughing is similar to 3 Axis Horizontal Roughing but is applied to rotated 5 Axis Setups. The clearance plane is an XY plane positioned above (+Z) the rotated 5 Axis Setup where the cutting tool approaches the cut start point from and where the cutting tool retracts from the cut end point.
 Dialog Box: Clearance Plane tab, 3+2 Roughing, 3 Axis |
This selection defines the Clearance Plane for the current toolpath operation. Automatic Allow the system to calculate a the clearance plane height automatically based on the part and stock geometry.
Part Max Z + Dist Set the Clearance Plane height to the maximum Z height of the Part plus this added distance.
Stock Max Z + Dist Select this option to use the Stock's Maximum Z height and then enter a Distance value to add to this for the total Z height for the Clearance Plane.
Absolute Z Value Select this to specify the absolute Z clearance height to use and then enter Z height value. Be sure that the value you specify clears your part geometry.
Ignore Wireframe Geometry in Bounds Computation Check this box to ignore all wireframe geometry when calculating the Clearance Plane definition. When checked, the Automatic and Part Max options for defining the Clearance will be calculated from actual surface geometry.  Ignore Wireframe Geometry in Bounds Computation |
When the clearance plane dialog is active, specifying a clearance plane definition, displays the clearance plane on the part in the view port.  Display of Clearance Plane for Milling operations |
