Paper Abstract

This paper states the cam's data processing algorithm in detail in high accurate camshaft measurement system. It contains: 1) using minimum error of curve symmetry to seek the center position of the key slot; 2) Calculating the minimum error by cam's curve in theory to search top area; 3) According to cam's tolerance E(i) function and minimum angle error at cam top, seeking the best position of cam top and getting the best angle value and error curve. The algorithm is suitable for measuring all kinds of symmetry or asymmetry cam, and plain push-rod or spherical push-rod cam, for example, bus camshaft, car camshaft, motor camshaft, etc. Using the algorithm, high accuracy measurement can be achieved.
