Research On Slotting Gear Numerical Control System Based On PC And DSP

In modern machinery and instrument industries,the application of bevel gear is increasing.Though numerical control processing is not fully realized in the current process of slotting bevel gear. Spiral guide is still used more to achieve additional rotation to machine bevel gear.But Spiral guide has many defects,such as complex technology required to manfacture it, high-cost, bad universal property, not getting compensation for abrasion.Utilizing the capability of high-speed digital signal-processing(DSP) chip of MCX314 to develop a bevel gear shaper processing system, replacing screw-driven servo system for the spiral guide, simplifying transmission mechanism, this has a very important practical significance and value.The following is the main content of this paper:(1) Introducing the current development of gear machining technology and the gear machining tool.(2) Analyzing the characteristics of forming a bevel gear; analyzing the bevel gear slotting process and dynamic analysis in the process.Putting forward the theory that uses undifferentiated methord to slot bevel gears.(3) According to idea of open CNC system, developing a bevel gear slotting numerical control system based on DSP and industry PC.Designing the hardware architecture and interfaces. On the basis of the hardware, designing system software control system on the Windows platform.Preliminary achieving slotting the bevel gear under numerical control processing.
