Further information
Permitted traversing commands, coordinate system
The following G commands can be used for the contour programming:
● G group 1: G0, G1, G2, G3
In addition, the following are possible:
● Rounding and chamfer
● Circle programming using CIP and CT
The spline, polynomial and thread functions result in errors.
Changes to the coordinate system by activating a frame are not permissible between
CONTPRON and EXECUTE. The same applies for a change between G70 and G71 or G700 and
G710.
Replacing the geometry axes with GEOAX while preparing the contour table produces an alarm.
Relief cut elements
The contour description for the individual relief cut elements can be performed either in a
subprogram or in individual blocks.
Stock removal independent of the programmed contour direction
The contour preparation with CONTPRON was expanded so that after it has been called, the
contour table is available independent of the programmed direction.
3.24.3 Generate coded contour table (CONTDCON)
With the contour preparation activated with CONTDCON, the following NC blocks that are called
are saved in a coded form in a 6-column contour table to optimize memory use. Each contour
element corresponds to one row in the contour table. When familiar with the coding rules
specified below, e.g. you can combine DIN code programs for cycles from the table lines. The
data of the output point is saved in the table line with the number 0.
Syntax
Activate contour preparation:
CONTDCON(<contour table>,<machining direction>)
Deactivate contour preparation and return to the normal execution mode:
EXECUTE(<ERROR>)
