Straight line interpolation

4.2 Straight line interpolation with mixed programming

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.

If any address letter "X", "Y", "Z" is not followed immediately by a numeri-

cal value, an equal-sign must be written instead.

X=IC(...), Y=AC(...), Z...

Programming example under G90:

N40 G90 G00 X40 Y48 Z2 M8

N50 G01 Z=IC(-14)

N60 X20 Y=IC(-30) Z-10

N70 Z2 F1000

Programming example under G91:

N40 G00 X=AC(40) Y=AC(48) Z=AC(2) To starting position P1 absolute

N50 G01 Z-14

N60 X=AC(20) Y-30 Z2

N70 Z=AC(2) F1000
