The set of the speed parameter of numerical control machine tool

The application of numerical control system according to numerical control machine tool circumstance, designed relevant speed parameter to every axis. It is axial top speed above all, this speed is numerical control machine tool sits actually the body of character again. The character of the rigid structure of axial top speed and transmission system and servo electromotor is concerned. Theoretic, it is 10mm when guide screw pitch, servo electromotor and guide screw are connected continuously, when the top rotate speed of servo electromotor is 3000r/min, the top speed of this axis is 3000mm/min. Actually, the reason such as the torsion of electromotor of the damp as a result of component of laden quality, motion, servo, effective rate of the axis is potential speed of short of theory. Additional, some axial distances may be very short, want to achieve very high rate, need very tall acceleration, in machinery of system of transmission of the need below this kind of circumstance the component has very tall tigidity, it is at the same time when servo electromotor type selecting, should choose the servo electromotor that deserves to have torsion of tall dynamic character, enough output. The axis of numerical control machine tool top speed is not decided by parameter of a machine tool, depend on however a lot of condition.
With the axis another parameter of top speed form a complete set is top speed limitation. The top speed limitation of set axis is very necessary, firstly the reason is axis of numerical control machine tool this goes to You Jing the meeting in the course that gives rate has speed to exceed tone. Special fall in the circumstance of tall acceleration, it is inevitable that speed exceeds tone. Because this cannot use axial top speed,regard speed as the limit. Another account that sets top speed restriction is OK when assuring to join in cable the mistake causes exceed the speed limit of make a present of of speed positive and negative, drive system is OK and automatic broken servo makes can, ensure the axis of numerical control machine tool won't damage because of overspeed.
