Changing of Linear interpolation positioning
explanation
B-62754EN/01-2
3 Details
The explanation of 4.1 POSITIONING (G00) Linear interpolation positioning is changed as follows.
(Before change)
Linear interpolation positioning
The tool path is the same as in linear interpolation (G01). The tool is positioned
within the shortest possible time at a speed that is not more than the rapid
traverse rate for each axis.
(After change)
Linear interpolation positioning
The tool moves along a line to the specified position. The tool is positioned
within the shortest possible time at a speed that is not more than the rapid
traverse rate for each axis. However, the tool path is not the same as in linear
interpolation (G01).
Note
The acceleration/deceleration of rapid traverse is the type of constant
acceleration rate, so the time of the acceleration/deceleration is not
constant. Therefore, when the linear interpolation positioning is
specified, the time of the acceleration/deceleration of the specified axes
is different from each other. As the result, the movements of the axes
have not been proportional to each other during
acceleration/deceleration, and the tool path may not be a line.
