摘要
随着激光技术的进一步发展和市场的不断扩大，光制造
技术将在所有制造领域内的许多方面取代传统的机械制造，激光微制造技术使微精密元件成为可能，并使微系统朝着多样化和智能化方向发展，最终在汽车、医疗和环保领域得到更广泛的应用，在国民经济和工业发展中起着日益重要的作用精密数控工作台采用滚珠丝杠副和滚动导轨副传动结构，具有精度高、效率高、寿命长、磨损小、节能低耗、磨擦系数小、结构紧凑、通用性强等特点。数控精密工作台系列可选择步进电机驱动，交流伺服驱动。
密数控工作台可广泛应用于激光焊接机、插线机、打孔机、涂胶机、机械手、搬运、检测装置、断层射线扫描、小型数控机床及实用教学领域。
我所设计的二加二维激光加工机正是基于2者的结合应用。众所周知，数控工作台在机械加工中已经有了不可替代的作用，因此，我们正是利用了它的种种优点，进行了设计，目的就是为了实现，伴随着工作台在四个方向的运动从而实现激光对工件的加工。

Abstract
Extend continuously along with the laser technical further development and markets, the light manufacturing technique will replace the traditional machine manufacturing in all manufacturing realms, the tiny manufacturing technique of laser makes tiny and precise component make possible, and make tiny system toward wear the diversification and intelligences to turn the direction development, end get the more extensive application in the automobile, medical treatment and the environmental protection realm, rise in national economy and industries develop the increasingly important function
Nicety the number controls the work set adoption to roll the bead silk 杠 vice- and roll over to lead the track vice- spread to move the structure, have the accuracy high, the efficiency is high, the life span is long and wears away small, economize on energy low consume, the coefficient of friction is small, the structure tightly packed, in general use strong etc. characteristics. The number controls the near work pedestal series eligibility to choose to tread into the electrical engineering to drive, communicate servo drive.
The number control the work pedestal and can be apply in the laser to weld the machine, patch cord machine, perforating machine, draw the gum machine, machine hand, transport, examine the device and break the layer to shoot the line to scan extensively, the small scaled number controls the tool machine and practical teaching realms
Keywords The number controls the work set Nicety the number controls the work set The laser process
