In contour grinding, grinding force varies in a complex way, because the curvature radius of a workpiece varies and the real depth of cut is also influenced by the thermal deformation of a machine structure. Since low stiffness tools are generally used in contour grinding, the fluctuation of a grinding force results in a lower machining accuracy. In this study, therefore, in order to establish the high precision contour grinding method, the reference position correct sensor is developed to compensate the thermal deformation of a machine structure, and the controlled normal force grinding technique is proposed to restrain the fluctuation of a normal grinding force. High performance contour grinding method, with which both constant surface roughness and high dimensional accuracy can be obtained in any curvature radius of a workpiece, is developed by using the controlled normal force grinding method with the reference position correct sensor.

In order to establish the high precision contour grinding method, the reference position correct sensor is first developed for compensating the thermal deformation of a machine structure, and then the controlled normal force grinding method is developed to control a fluctuation ofa normal grinding force. Main conclusions obtained in this study are as follows : (1) It is made possible to correct the error of wheel depth of cut accurately, with using developed reference position correct sensor. (2) The controlled normal force grinding technique is developed, through the analysis of the feed rate setting conditions correspond to the curvature variation of a workpiece. (3) High performance contour grinding method, with which both constant surface roughness and high dimensional accuracy can be obtained in any curvature radius of a workpiece, is developed by using the controlled normal force grinding method incorporate the reference position correct sensor.

The partial contacting wear test of spray coated ceramics was carried out by using pin-on-disk type wear testing machine. The test results of spray coated ceramics with no treatment were compared with that of Ni-P + PTFE plated spray coated ceramics. And observation of wear surface was carried out using together some methods of observation in order to analyze the wear surface in initial break-in condition quantitatively.<BR>The main results are in the following : Spray coated ceramics was worn abnormally after partial contacting wear test, but Ni-P + PTFE plated spray coated ceramics was worn normally, protecting from the damage by partial contacting. Phenomenon of surface break-in condition can be evaluated quantitatively by statistical treatment of wear surface profile.
