Abstract
New techniques are presented for cam profile measurement and evaluation based upon recently derived analytical methods and electronic computer programs. The new methods include the mathematical refinement of profile raw lift data and obtain the following advantages over current practice:
-
1.
Accuracy-Cam profile lift data accuracy is improved by a factor of ten to one hundred times.
-
2.
Repeatability-The profile measurements and evaluations are repeatable within the new limits of accuracy.
-
3.
Evaluation-“Camcheck”* computer programs yield new information which has optimum usefulness to quality control and engineering design development.
-
4.
Efficiency-The new analytical methods essentially eliminate camshaft manual set-up procedures for profile measurement-and also substantially reduce the engineering time required for profile evaluation.
In conclusion, new acceptance criteria for cam profile quality control, and the direction for the further development of cam profile measurement and evaluation methods and techniques are suggested.
