4.2.12. POSITION OFFSET IN X- AND Y-AXES (G45 TO G48) (Cont'd)
(5) Length for Extension or Reduction
(a) One or two times the programmed offset length is added or subtracted, selectively.
See Fig. 4.16.
(b) When the motion has been extended or shortened by offsetting in the preceding block,
the starting point for the present block is offset. The overall move distance, however,
is the same as in the above case. See Fig. 4.17.

(6) Application to Circular Interpolation
When I, J, K, R are programmed in the same block with G45 to G48, extension or
reduction is made respectively in the same direction as X, Y, Z. Therefore, radius
compensation is possible with 1/4 circle, or 3/4 circle only.
