OPMODE 1: Insertion of transfer polynomials

In free form operation mode 1 at movement block transitions the blocks are shortened and transfer polynomial are inserted.

From the maximum contour error CONTERROR ("ε") the corner distance "a" is calculated. This value is necessary for the generation of the polynomial transition. That means, the inserted polynomial reduce the actual contour error.

OPMODE 2: Generation of spline curves for free form parts

In free form operation mode 2 spline curves are generated through the given edge points. At the beginning of prismatic parts the spline generation is automatically deselected and a tangential transition is carried out.

At block transitions in prismatic parts, which were detected based on the additional parameters of chapter 11.17.1.2, it is changed automatically into operation mode 1 (OPMODE 1), this means transfer polynomials are inserted. For the inserted spline curves no contour deviation between the vertices is monitored.
