Converting Linear Motions to Arcs
The following new variables control the way GPP2 applies the arc-fitting algorithm that converts a series of linear motion blocks into arcs:
|
System Variable |
Default format |
Use and Comments |
|
ARCFIT_PLANES |
6 |
Determines the planes where GPP2 looks for arc fitting. The variable is initialized from the corresponding DF2 parameter, to one of the following predefined values: DEF_NONE (1) DEF_XYONLY (2) DEF_MAJORPLANES (3) |
|
ARCFIT_TOL |
1 |
Tolerance used in the arc fitting process. Initialized from a DF2 parameter. The actual tolerance used also depends on the DF2 parameter that defines the tolerance "type" - Procedure or Absolute. |
|
ARCFIT_MIN_CNT |
6 |
The minimum number of points that can be approximated by an arc. No arc will be created if a proper (within tolerance) arc cannot be found with this number of points. Initialized from a DF2 parameter. |
|
ARCFIT_HELICAL |
6 |
Determines if helical arcs (for helical plunge) are supported or not. Initialized from a DF2 parameter. If set to TRUE_, GPP2 will also search for helical arcs in the XY plane (only). If set to FALSE_, GPP2 will ignore helical arcs. |
