The invention discloses a control method for a planar conjugate cam contour detecting and grinding device. The technical point is that when a grinding wheel grinding head of a grinding mechanism of a grinding controlling and detecting device performs grinding on an outer contour of a planar conjugate cam, a second laser measuring head of a cam inner contour …
Abstract: Based on the current situations of grinding error analysis and compensation, a new contour error analysis and compensation method was proposed for camshaft CNC grinding in X-C axis linkage, to improve the accuracy of cam grinding.
The cam contour error directly reflects the cam contour accuracy. Considering the deviation of cam grinding after speed optimization, contour compensation contr

Other than routine design work I can see no great theoretical difficulty in making a cam grinder to grind the contour of automotive cams from scratch. Whether the acccuracy and uniformity of the cam profile thus obtained is suited for even a garden tractor much less a high specific output automotive engine is a matter of trial - but I would expect a miserable failure.

Abstract: The CNC cam grinding contour accuracy is influenced by the complexity of the cam profile and periodic disturbance caused by end effect and friction of the grinding system. In order to enhance the contouring performance, a …
With non-cylindrical grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis). CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life. The cam geometry is specified in a elevation table.
with the grinding wheel diameter, which will be used during grinding process. Instead of roll a grinding wheel, having the diameter equal with roll diameter, which will be used during cam contour grinding process. Command cam has to be approximately milled, and using the above-described installation of components will be grinded directly on the ...

What is the abbreviation for Cam contour grinding? What does CCG stand for? CCG abbreviation stands for Cam contour grinding.
The rotary angle and length of travel (x) of the grinding wheel are adjusted in response to the polar coordinates of a nominal contour of the cam, supplied by a numerical control, while the...
A method serves for grinding two or more cams of a camshaft. Initially the camshaft is chucked in a mounting position between a driver of a work headstock seated to rotate about a first axis (C axis), and a footstock. Then the camshaft is rotated in a defined rotary angle/time relationship. A rotating grinding wheel is advanced in the direction of a second axis (X axis) extending ...
