On the base of analyzing the specialty of the non-circle gear and the technology of its numerical control machining

appling the computer programming technology to disperse the ellipse pitch curve

the non-circle gear numerical control machining system is developed based on industrial personal computer. The configuration of the system’s hardware

the principle of interpolation and program designning are stated. The dissertation recountal the real-time technic measures of the NC system. The system’s hardware has high openning degree

simple structrue and stable state. On-line programming

simulation

real-time machining and dynamic tracing display for non-circle gears can be conducted by means of this system.
