With the continuous development of computer technology, Chinese scientific level to further enhance the CAD / CAM technology gradually mature, and in the aerospace, construction, electronics, machinery, automobiles and other fields are widely used, and in the machinery industry, gear Transmission is one of the most common transmission methods, the effective transmission of sports and power parts, the successful completion of the commutation, change, speed, deceleration and other actions, which put the gear parts put forward higher requirements. This paper mainly analyzes and studies the UG platform, the significance of UG platform in gear CAD design and the gear CAD design analysis based on UG platform, which is helpful to strengthen the design of UG platform in gear CAD design. Application provides a reference.

Faults such as without cooling when processing, chuck could not clamp work pieces and turret without rotation were presented in CNC machine tools in this paper. Make use of PLC status display information diagnosis machine tool fault can get rid of fault rapidly and effectively. Practice has proved that it is an effective method to use PLC diagnosed fault.
