Control method of numerical control duplex head milling machine and corresponding control system thereof

Abstract

The invention belongs to the technical field of numerical control milling machine, and in particular relates to a control method of a numerical control duplex head milling machine and a corresponding control system thereof. The control system includes a process parameter acquisition module, a material pressing module, a left and right milling head start timing determining module, a left and right milling head Y-axis positioning module, a left and right milling head main primary motion driving module, a milling table X-axis feeding module and a material unloading module. The control method includes a process parameter acquisition step, a material pressing step, a left and right milling head start timing determining step, a left and right milling head Y-axis positioning step, a left and right milling head primary motion driving step, a milling table X-axis feeding step and a material unloading step. The control method and the control system disclosed in the invention can optimize the specific time to start the primary motion of left and right milling heads by the organic cooperation of the various functional modules or the process steps, thereby effectively reducing the idle energy consumption of the left and right milling heads and improving the energy utilization rate of the milling machine.

Description

technical field [0001] The invention belongs to the technical field of numerical control milling machines, and in particular relates to a control method of a numerical control double-head milling machine and a corresponding control system. Background technique [0002] CNC double-head milling machine refers to a milling machine with two left and right milling heads arranged symmetrically or asymmetrically on both sides of the milling table feed track (hereinafter referred to as X-axis movement or feed movement), in which the left and right milling heads rotate The milling movement is mainly Motion, the relative motion between the milling table and the milling head is the feed motion. Since multiple milling surfaces of the workpiece can be milled at the same time, and the number of clamping of the workpiece can be reduced, this kind of milling machine can double the processing efficiency of the production line and the processing accuracy of the milling machine. The existing ...

AI Technical Summary

Problems solved by technology

The existing CNC double-head milling machines generally use the active movement of the milling table to realize the feeding of the workpiece. Before operation, the left and right milling heads are positioned in advance to the appropriate positions corresponding to the milling surfaces on both sides of the workpiece, and the left and right milling heads feed The main movement of the left and right milling heads starts at the same time or after the feed is completed; this may cause the following problems: due to the different sizes of the parts to be processed, when processing smaller-sized parts, the milling table moves from the initial position It takes a certain amount of time until the left and right milling heads start to touch the part. During this period of time, the left and right milling heads will idle, which will increase the energy consumption of the milling machine needlessly.
