Abstract： The traditional machine tool is driven by hydraulic pressure system and controlled by relays and contactors，so the control performance is not good and the scheme is designed and tested difficulty. Aiming at these problems，PLC and touch screen were used instead of relays and contactors to control the hydraulic system in the modular machine tool. The work flow of power sliding feed was an alyzed and the type of PLC was selected. The hardware and software of control system were designed basing on the work flow. It was programmed with the software Gx-Developer and the control program was tested with the software Gx-Simulator to ensure which could satisfy the use requirement. The results indicate that the control performance and the design efficiency are proved.
