Question:

The machine strongly reduces the feed rate, especially in curves. I create the program in a CAD/CAM system, which only outputs linear blocks. The defined feed rates are very high at times (up to 10 m/min during roughing). Does the control not have enough processing capacity? Or is there another solution?

Answer:

The problem is most likely not caused by the control’s processing capacity. The control simply maintains the settings of the machine it is connected to (acceleration, jerk, tolerance, etc.). You can basically influence the possible contour speeds with Cycle 32 (DIN/ISO G62). The greater the tolerance, the higher the possible contour speed. This tolerance also affects circular motions. Please note, however, that the chord error of the NC program (can be set in almost all CAM programs) should be no more than half of the permitted tolerance (Cycle 32).
