With the development of science and technology, all walks of life are also quietly changing, among which, laser cutting processing with invisible light beam instead of the traditional mechanical knife, laser cutting precision is high, cutting speed is fast, not limited to cutting pattern restrictions, automatic typesetting save materials, and smooth incision, low processing costs, Laser cutting is gradually improving or replacing traditional metal cutting process equipment.

Laser cutting machine is generally composed of laser generator, host frame, motion system, software control system, electrical system, laser generator, external optical path system. One of the most important is the laser generator, which directly affects the performance of the equipment. The transmission structure of laser cutting machine is generally synchronous wheel synchronous belt transmission, synchronous belt transmission is generally called meshing belt transmission, through the inner surface of the transmission belt equidistance distribution of transverse teeth and the corresponding tooth groove on the belt wheel meshing to transfer movement.

At present, the laser cutting machine on the market is a set of motion system for cutting operations, and the laser cutting head is driven by the motor for X, Y, and Z three directions for moving cutting, which can be cut by the pattern of a single motion trajectory.

With the continuous development of laser cutting technology, the processing capacity, efficiency and quality of laser cutting are constantly improving. However, in the existing laser cutting machine are a set of motion system, in a single or single version of laser cutting requires that the pattern must be the same or mirror pattern, in the laser cutting typesetting has limitations, can only carry out a single single graphic typesetting corresponding to only a set of processing trajectory can be achieved, and can not achieve efficiency.

To sum up, how to effectively solve the limitations of single graphics typesetting and low cutting efficiency is an urgent problem for technicians in this field.
