An application of the three coordinate machine to the measurement of both the helical error and the tooth shape error happened to the cylindrical indexing cam contour surface is proposed in the paper.

A method of non-contact on-line measurement for measuring plate cam contour is proposed in this paper.

On applying the theory of differential geometry, the research shows the procedure for determining the required cutter path for cutting conical cam profile using a NC milling machine based on the analytical profile expression of conical cam with oscillation conical roller follower or with a translating conical roller follow.

On applying the theory of differential geometry,the research presented in this paper shows the procedure of determining the required cutter path for cutting conical cam profile by using a NC milling machine based on the analytical profile expression of conical cam with oscillation conical roller follower established in 3D space.

Reverse seeking method on motion law of parallel indexing cam mechanism based on cam contour;

The machining quality of cam contour is a key fact to impact the operating property of a cam mechanism.

A general-utility cam contour CAD system is developed by taking advantage of C ~(++) Builder.

In this paper it mainly states the equation on applying analytics to establish the cam outline curve and the cutting tool center orbit,thus we can work out the coordinate value and pressure angle from the every point of the cam outline line,we also can machine the cam outline on the numeral control machine tools and check the performance of the transmission force.

The cam outline date were calculated by C language programming and the calculation function warehouse of cam outline was constructed.

The proposed method provides an availability thought for 3D design of parameterized cam outline.
