Polynomial contouring type 1

In the case of polynomial contouring type 1, not only the corner distance but also the axis acceleration and the programmed nominal feed rate are used for calculation. If permitted by the user-specified contour and parameters, the contouring path is run through without a speed drop as far as possible. If the programmed feed rate is very high, the acceleration and the corner deviation are the speed-limiting parameters.

No kinematic transformations are considered in estimation of the corner distance.
