Straight line interpolation
Section 4
The example shown below describes the milling of the slot with mixed
cordinates input.
Program blocks such as the call-up of the tool etc., which have already
been dealt with, will not be repeated.
Important:
If any address letter “X”, “Y”, “Z” is not followed immediately by a numeri-
cal value, an equal-sign must be written instead.
Syntax: X=IC(…), Y=AC(…), Z...
