Radius compensation
The radius compensation must be in the block in which you move to
the first contour element. You cannot begin radius compensation in a
circle block. It must be activated beforehand in a straight-line block
(see “Path Contours—Cartesian Coordinates” on page 213) or
approach block (APPR block, see “Contour Approach and Departure”
on page 205).
Pre-positioning
Before running a part program, always pre-position the tool to prevent
the possibility of damaging it or the workpiece.
Creating the program blocks with the path function keys
The gray path function keys initiate the plain language dialog. The TNC
asks you successively for all the necessary information and inserts the
program block into the part program.
Example—programming a straight line:
Initiate the programming dialog, e.g. for a straight
line.
Enter the coordinates of the straight-line end point,
e.g. –20 in X.
Enter the coordinates of the straight-line end point,
e.g. –30 in Y, and confirm with the ENT key.
Select the radius compensation (here, press the R0
soft key—the tool moves without compensation).
Enter the feed rate (here, 100 mm/min), and confirm
your entry with ENT. For programming in inches,
enter 100 for a feed rate of 10 ipm.
Move at rapid traverse: press the FMAX soft key, or
To traverse with the feed rate defined in the TOOL
CALL
block, press the FAUTO soft key.
