Involute Curve

In order to process the involute curve profile of scroll compressor，the method of using Archimedes spiral to approximate the involute curve in the polar coordinates is used.The error of approximation caused by different interval distances of interpolation points is simulated by Matlab.The machining experiment of orbit scroll using the appromation method of equal-radial- interval is carried out on CNC machine tool,and the interpolation error of actual machining is . The effectiveness and practicality of the method were tested and varified.

This paper presents some simulation based upon a dynamic model of a feed-drive within the structure of a CNC machine tool. A DC servomotor was considered as actuation device for the feed drive. For a given set of parameters for the position controller, two fuzzy types of fuzzy controllers were tested by means of simulation. The first fuzzy controller was a proportional one, with one input and one output, while the second one was a two variables one, with two inputs and one outputp.
