This study aims to provide a sound knowledge about the motion controller, including the principle, method and procedure. The subjects of the interpreter, cutter compensation, acceleration control, interpolator, are discussed in the thesis. the portion of the interpreter which consists of the linked list stacks, it can simulate the BASIC-Like logical control, language and standard NC program and transforms the original NC program to a program which exclude compensation and cycle code . The interpreter also can expand the NC code, according to the job requirement. The portion of cutter compensation is to use method of coordinate rotation to simplify the procedure of the This will greatly benefit to those who want to calculate the compensation by using the computer design program. For the portion of the acceleration control, interpolator, they provide a simple and feasible manufacturing method and this is benefit to design and manufacture of the motion controller.
