Machine halt energy conservation implementing method in no-load running period of adjacent process steps of numerical control machine

Abstract

The invention provides a method for implementing shutdown for energy conservation in idle running between adjacent process steps of a numerical control machine. The method comprises the following steps: before machining, according to the operation speed of a mainshaft obtained by a machining process and the spacing interval between the adjacent process steps determined when the numerical control machine programs, the idle running time between the adjacent process steps is obtained; and the control time and the energy conservation percentage when reboot after shutdown for energy conservation is implemented between the adjacent process steps are calculated by a testing data table and a curve fit method. When the energy conservation percentage is a positive number, a shutdown instruction and a subsequent reboot instruction are embedded in a numerical control program according to the control time, thereby achieving the effect of the energy conservation of the machine. With regard to the problem that a main transmission system has energy loss in idle running between the process steps of the numerical control machine, the method adopts a mode of the reboot after the shutdown to reduce the idle running time of the machine in the mechanical manufacturing process and to achieve the aim of energy conservation.

At the same time, a large number of statistical surveys show that the average utilization rate of machine tool energy is low, less than 30%.

When these actions are in progress, although the main transmission system of the machine tool does not perform production and processing actions, it does not stop moving, and there is still energy transmitted from the machine tool motor to maintain their motion requirements, resulting in energy loss of the machine tool

The energy loss of the main transmission system in the process of machine tool no-load is a kind of extensive energy loss, and it is also one of the direct reasons for the low energy utilization rate of the machine tool
