SINUMERIK 828D, 840D sl: Avoiding vibration in slewing gear pieces
Permanent change in speed of the master spindle can eliminate any vibrations occurring in the slewing gear piece. When manually changing the spindle speed by using the override, it is very difficult to create a harmonious vibration speed of the master spindle. Therefore, a cycle which consists of two part subprograms (.SPF files) should be created. By selectively switching the cycle on and off, a harmonic vibration speed of the master spindle is forced. Both subprograms of the cycle form the basis for future use of the "OSZI" command, which can be safely used in the program GUIDE (G-code).
