Aimed at the complexity of non-circular gears design and manufacturing process, according to the principles of gear connection, the pitch curve mathematical model of high-order elliptical gears is established. The pitch curve meshing characteristic and transmission ratio of high-order elliptical gears is calculated and analyzed using MATLAB software. Based on the converting tooth profile method, the...
A solution for integrating CAM (Computer - Aided Manufacturing) systems into multi-axis nutating table CNC (Computerized Numerical Control ) machines is presented in this paper. The strategy of the method is to build a CL data processing algorithm. Thus, the CL data in ISO format produced by every CAMs can be transformed and translated into G-codes files (Numerical Control files) for controlling CNC...
We develop a Windows based cam design and manufacturing simulation system. First, general equations for the profile of disc cam are derived by defining 3 parameters, the direction of cam rotation, direction of follower bias and forward & backward bias, which greatly simplifies the computer programming for the computation of coordinates of cam profile. Then, a parameterized three-dimensional cam...
