摘要：worm and worm gear are modeled under development environment in AutoCAD based on the principle of ordinary cylindrical worm drive. The drawing commands available in AutoCAD are used to develop worm blank and cutter models. The solid models of worm and worm gear are obtained through the use of the commands, move, rotate and subtract, to simulate the generating cutting movement on the gear cutting machine. Autolisp language is utilized in programming for parametric modeling of worm and worm gear. The developed program can automatically draw worm and worm gear when users load the wlwg program, input the modulus and the number of threads, handedness, and other parameters. The operation is simple and accurate, providing potentials to speed up product design process and improve efficiency.

摘要：This paper presents a detection method for hourglass worm based on follow-up pre-positioning technolo-gy, by establishing theoretical model of the corresponding relation between the movements of the worm and theprobe. The probe coordinate of next sample point is mapped through the actual motion coordinate measured ateach sample point. And then the probe is located to the next sample point in advance by using the precision mo-tion control based on time subdivision. This detection method can realize online servo measurement for machiningerror of hourglass worm and actual space spiral measurement under specific throat radius. The actual surface con-tour of hourglass worm is constructed by helixes in different throat radiuses, then the machining error can be ob-tained by comparing the contour with theoretical model. The detection system, which includes host and slave sub-systems, is designed according to this method.
