(2) Method of determining the tangent acceleration
Acceleration/deceleration is performed with the largest tangent
acceleration/deceleration that does not exceed the acceleration set for each axis.
(Example)
X-axis permissible acceleration: 1000 mm/sec
2
Y-axis permissible acceleration: 1200 mm/sec
2
Acceleration change time: 20 msec
Program:
N1 G01 G91 X20. F6000 Move on the X-axis.
G04 X0.01
N2 Y20. Move on the Y-axis.
G04 X0.01
N3 X20. Y20. Move in the XY direction (at 45 degrees).
The acceleration in N3 is 1414 mm/sec
2
. At this point, the acceleration on the X-axis
is equal to the set value (1000 mm/sec
2
).
