Abstract
In order to further improve the feed accuracy of the ordinary machine tool workbench, the machine tool processing equipment feed control system based on servo motor, PLC and MCGS touch screen is designed.Through the system hardware and software design, the effective control of the cross slide platform is realized.Using the touch screen to modify the workbench operation parameters online, it can meet the processing requirements of a variety of material workparts, and improve the processing efficiency.The actual processing operation shows that the control system can fully meet the demand of production and processing precision of equipment and has promotion value.
It is proposed that PLC control stepping motor and servo motor are applied to the motion direction of XY axis of cross slide platform. Due to the high control precision of stepping motor and servo motor, precise positioning can be realized, the working efficiency and quality of cross slide platform can be improved, and the requirements of modern process development are met.Build the PLC, the step motor control system and the servo motor control system, and actually apply the PLC control step motor and the servo motor to the cross-slide table control.
This paper mainly conducts the design of the cross slide control system of OmCP1H programmable controller, including cross slide control system introduction, cross slide control system hardware selection, ladder diagram and I / O allocation.Select the comparison of various control methods to control the stepping motor for the cross slide.
Keywords: machine tool; stepping motor; cross slide table; XY axis; PLC
