General Properties
The process of the geometrical polynomic contouring bases on the path contour of the main axes in all three dimensions. The corner distance results from the predefined settings like corner deviation or percentage path velocity. This means, the starting point respectively the target point of the polynomic on the original path is known.
From the calculated corner distance of the main axes also the corner distance of the slave axes can be determined. In the same manner like for main axes also for slave axes between the corner distances of the pre- and the post-block under consideration of the maximum acceleration of the axes a curvature and direction-continuous polynomic is inserted.
The possibly specified limit for the corner deviation just considers the main axes. Therefore, a separate limit for the deviation of the slave axes can be specified. Any theoretical exceeding of this deviation by a slave axis causes a reduction of the contouring curve (deceleration of the corner distance).
The polynomic contouring automatically is suppressed if:
- the movement of the all axes is tangential or directly is mirrored.
- the movement of just the main axes is tangential and no maximum deviation of the tracking axis is specified (value = 0).
- after G61 the program end without any post block is reached. Additionally a warning message is raised.
