Title:
SPINDLE DECELERATION ENERGY-SAVING METHOD FOR NO-LOAD PROCESS BETWEEN ADJACENT CUTTING ACTIVITIES OF NUMERICAL CONTROL MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2024/050913
Kind Code:
A1
Abstract:
A spindle deceleration energy-saving method for a no-load process between adjacent cutting activities of a numerical control machine tool. The method comprises: collecting a state rotational speed of a spindle and a no-load interval time between adjacent cutting activities; acquiring energy consumption of a numerical control machine tool in each motion state; on the basis of the state rotational speed of the spindle and the energy consumption of the numerical control machine tool in each motion state, acquiring energy consumption of the machine tool in a no-load motion process and energy consumption during the implementation of a spindle deceleration strategy; and presetting a precondition for energy saving, when the energy consumption of the machine tool in the no-load motion process, the energy consumption during the implementation of the spindle deceleration strategy and the no-load interval time meet the precondition for energy saving, acquiring a spindle deceleration energy-saving critical time, and when the no-load interval time is greater than the spindle deceleration energy-saving critical time, performing spindle deceleration in a no-load interval. By means of the method, the rotational speed of a spindle during no-load operation of a numerical control machine tool is decreased to reduce energy consumption of the machine tool in a no-load process, so as to increase the energy utilization rate of the machine tool, thereby avoiding the loss of a main transmission system and an electric motor caused by frequent starting and stopping of the machine tool.
