Design Of The CNC System Of 5-Dof Parallel Machine Tool

Parallel machine tool is a synthetical subject. It involves many science fields such as mechanism, electron, autocontrol ,computer, sensor. After more than ten years research, we still need to practise new theories and do more experiments.This thesis analyses the characters of parallel machine tool from the kinematics and discusses many methods to forward direct ? Using the 6 degree mouse we can control simulation of 5-Dof parallel machine tool which was made by OpenGL. It put forward the differences between parallel machine tool and traditional machine tool from hardwares and softwards. It also get much knowledge from doing experiments.It is necessary to analsys the kinematics. By the analysis of velocity and positon of 5-Dof parallel machine tool, we build a simulation in dummy environment By computer programm. We can check the workspace and performance.For the hardware of CNC system we use the PMAC controller which embedded in the computer mainboard. Set the parameter of PMAC. Using DPRAM to connect PMAC and IPC. It also introduce the other devices in details such as servo system .We use OOP(operate oriented programm) to make our program. All the functions are encapsulated in classes. Between classes it is high cohesion and low coupling.The software can carry out movements of jog , auto run, searching home and so on. It includes two aspects which are user interface and data disposal. Translate and edit the NC codes and use a good way to deal with velocity of 5-Dof parallel machine tool. It argues how to find the start position and use PLC to monitor the system.
