Research of influence of errors of cam manufacturing on the law of motion of output element

Abstract

Insignificant error in the moment of manufacturing the mechanism can influence significantly on its’ work. Research of influence of manufacturing error with manufactured mechanism usually is irrational, that’s why necessity of evaluation at the stage of design occurs. Methods of evaluation of this influence are investigated in this paper. The research is implemented by developed algorithm, which also was realized in MATLAB and Python as well. Due this fact process of math simulation doesn’t occupy a lot of time and doesn’t need large calculating abilities. We research same data by independent ways by using 2 different programs and we compare results in order to check and improve model. Also, it’s interesting that technology of computer vision was applied in this work. So, presented paper will be interesting for everybody who practice design of cam mechanisms or research them.

Cam Mechanisms Reverse Engineering Based on Evolutionary Algorithms

“…The choices for the cam manufacturing, such as the material, the production technology, the tolerances chosen in the design phase and the accuracy of the CNC machinery, can instead influence the follower law of motion. Samsonenko in 2020 in [26] researched the influence of errors of cam manufacturing on the law of motion of the output element and concluded that slight deviations of the cam shape from the ideal can lead to significant deviations of the movement's law of the follower. Therefore, a correct choice of the manufacturing method of the cam and of its tolerances is fundamental for the effectiveness of the proposed method.…”
