So, CNC laser cutting has been playing an important role in Chinas manufacturing industry.This paper describes the design of a SCM-controlled CNC laser cutting machine tools. More attention was paid on the overall machine design, Z axis, XY axis in the design, ball-screw and the choice of linear motion guide and intensity analysis; the drive system into which stepper motor was put and the analysis of the drive system design; 89C51 chip was mainly used for the design of hardware circuit, the design of system initialization and the design of stepper motors controlling program.Key words CNC, laser cutting machine tools, architecture, designII
