Contour definition programming
Functionality
If the end points for the contour are not directly specified in the machining drawing, it is also
possible to use an angle specification ANG=... to determine the straight line. In a contour
corner, you can insert the elements chamfer or rounding. The respective instruction CHR= ...
or RND=... is written in the block, which leads to the corner.
The blueprint programming can be used in blocks with G0 or G1 (linear contours).
Theoretically, any number of straight line blocks can be connected and a rounding or a
chamfer can be inserted between them. Every straight line must be clearly identified by point
values and/or angle values.
