(a) With linear acceleration/deceleration
Previous block
(b) With exponential acceleration/deceleration

(c) With exponential acceleration/linear deceleration
Previous block
The time required for the deceleration check during cutting feed is the longest among the
cutting feed deceleration check times of each axis determined by the cutting feed
acceleration/deceleration time constants and by the cutting feed acceleration/
deceleration mode of the axes commanded simultaneously.
(Note 1) To execute exact stop check in a fixed cycle cutting block, insert command G09
