The Device Design Of Multi-Function Micro EDM Base On PMAC

With the aerospace industry rapid to develop, micro-EDM technology continues applied more and more widely in the aviation and aerospace fields. Due to the particularity micro-EDM technology, in the process compared with the traditional processing have a non-contact, no macroscopic characteristics of cutting force, so the micro-EDM technology have been greatly developed in many countries of the world. In this paper, after reading a lot of literature and reference information at home and abroad carried out based on PMAC versatile micro-EDM devices.The first chapter begins with a brief history of the development of micro-EDM. By comparing the status at home and abroad describes the current state of micro-EDM development. Which is divided three parts. Included CNC EDM,EDM spindle system and EDM technology. Because the micro-EDM machining compare conventional machining have a clear distinction and its own particularity, EDM requires careful overall consideration to design process to meet its own characteristics. So considering all aspects of micro-EDM requirements the second chapter gives the micro-EDM based on PMAC multifunction device overall design. This article will introduce the three parts of the overall design.The third chapter is machine tool structure design based on micro-EDM machine. In order to guarantee high precision of micro-EDM, the mechanical structure of the device design selection process is a very important part Multifunctional Micro-EDM machine parts mainly divided into:platform, X, Y, Z axis feed system, rotary head unit, the working fluid tank (bench) and the working fluid circulation system, as well as stents. The machine tool design is the design of the mechanical parts contain feed, column, platform, spindle for clamping the electrode and the work-piece mechanical parts and other components. The fourth chapter is based on the PMAC servo control system designed,in this paper,PMAC is the core unit of the control system open architecture. PMAC is one of the world’s most advanced, most powerful and base on pc open motion controller. Servo control system by running the PMAC internal PLC program and exercise program to achieve three-axis control and multi-functional micro-EDM at runtime state monitoring and control tasks executing agency to complete the multi-functional micro-EDM servo control processing systems. The fifth chapter is the man-machine interface. This article uses Visual C++and MFC development tools to develop interactive interface PC application. Including development of the system architecture design, analysis module, as well as specific functional modules. Application software is to complete the entire machine interface control system management tasks. For the servo loop updates,interpolation calculation bit computing tasks such as control by PMAC completed. The main article HMI is a very user-friendly interface for non-professional use.
