Abstract

A tool feeding speed profile is directly programmable, feeding speed minimums across the control blocks being used in advance in the event that the admissible axis dynamics are exceeded by the predefined feeding speed profile. The tool feeding speed profile can be programmed, in particular, as a linear, polynomial, or cubic feeding speed profile, the latter being predefinable over a sequence of control blocks as a feeding speed polynomial or a feeding speed spline by interpolation or approximation.
