Design And Realization Of An Assisted Machining Platform For The Twin Face Lathe

There are many problems affecting the quality of machining of the compressor disk. The main problems is high surface roughness of workpiece caused by cutting force and heat of the large diameter and thin wall disk of difficult processing materials, and surface profile error of workpiece caused by axial error of large diameter spindle in the rotation of the twin face lathe. The paper puts forward two methods to solve the problems above, one is high frequency vibration assisted machining, another is servo tool assisted machining, then a task of design and realization an assisted machining platform based on the vibration cutting device and servo tool device. The main propose of the platform is controlling the devices work stably to reduce surface roughness and profile.The assisted machining platform use industrial PC to control the high frequency vibration assisted machining device and the servo tool machining device by acquiring signals and sending instructions to these devices by data acquisition card installed on the industrial PC. In the terms of hardware, after analyzing electrical characteristics of the devices, the paper mainly describes how to design controlling and data acquiring circuit, power supplying circuit and ergonomic operating platform, then install electrical components in accordance with the relevant standard; And in the terms of software, it analyses functions of the software and realization methods, then describes the designing of human-computer interactive interface and controlling program which can control the assisted machining devices automatically.After designing and debugging the assisted machining platform, and operation experiment, the assisted machining for the twin face lathe can work stably. The actual machining experiment indicate that the assisted machining platform can effectively reduce the surface roughness and profile and achieves the design purpose.
