Basic Theory
This describes and analyzes the additive offset, coordinate rotation,
scaling functions mentioned above.
Machining target dimension drawing and the final effect are as follows:
Drawing 1—original workpiece
machining
Drawing 2—coordinate rotates
100º
Drawing 3—①Drawing 2 along
X axis mirror image
②Coordinate rotates 20º
Drawing 4—①Drawing 3 along
Y axis moves 60 in
negative direction
②enlarge 1.3 times in X
and Y direction

N65 milling rectangular groove（depth 5 mm,
length 30 mm, width 15 mm, corner radius 3
mm, groove datum coordinate (X-28,Y30),
groove longitudinal axis and plane X axis

N100 coordinate axis rotates -20º in positive
direction
N105
N110 machining the same groove at the new
position
N115 coordinate axis rotates –10º in
negative direction
N120 Y axis coordinate moves 60 in negative

In this example, the positive
direction of the XY
coordinate axis is different
when machining each
groove!
