The numerical control engine bed is the digital process control engine bed, is one kind of automated engine bed, the numerical control technology is the core which the numerical control engine bed studies, is the manufacturing industry realization automation, the network, the flexibility, the integrated foundation. Along with the manufacture technology development, the modern numerical control engine bed with the aid of the modern design technology, the working procedure intensification and the new function part caused the engine bed the processing scope, the dynamic performance, the processing precision and the reliability had the enormous enhancement .
This article mainly carries on the design to the XK5040 numerical control vertical milling machine and the control system, first analyzes the vertical milling machine the processing characteristic and the processing request determines its host parameter, including movement and dynamic parameter; Carry on the host kinematic scheme according to the host parameter and the design request, enters for the system and the control system hardware circuit design. Mainly carries on the host kinematic scheme and enters for the system mechanism design and the ball bearing guide screw and electric stepping motor shaping and the examination; Regarding control system because here mainly aims at the economy numerical control milling machine the design, here uses electric stepping motor open-loop control, the computer system uses the high performance price compared to the MCS-51 series monolithic expansion system, mainly carries on the central processing element the choice, the memory expansion and the connection circuit design .
Key words Numerical control technology; Vertical milling machine; Design
