Study on Machining Error of Globoidal Cam Profile Resulting from Motion Error of Machine Tool in Machining
The profile error of a globoidal cam resulting from motion errors of two coordinated rotational axes of a machine tool in machining is studied. A novel method of solving profile error is presented. According to this method, the minimum distance from a point on the profile actually machined to the- desired profile is referred to as the profile error. Then, the mathematic model of profile error resulting from the motion errors of the machine tool is built. After that, the type TC40 globoidal cam is employed as an example to analyze the machining error. The linear influence coefficients of the motion errors of the two coordinated rotational axes on the profile error are determined. The maximum value of the machining errors resulting from the motion errors of the two rotational axes of machine tool is yielded. A novel method of improving the velocity of solving the maximum value by using the linear influence coefficient is presented. At last, an isogram is introduced to analyze the influence of the motion errors of the two coordinated rotational axes of the machine tool on the globoidal cam profile error.
