The use of thermal spray coatings is increasing to improve abrasion resistance, erosion and corrosion resistance. To improve the dimensional accuracy or surface roughness, it is often necessary for thermally-sprayed machine parts to be machined by the removal process. As thermally-sprayed coatings often show difficult-to-cut properties, a cutting, grinding, or honing process is usually employed. Replacement of the grinding process with a cutting process is an effective method for improving productivity. Cutting is performed intermittently because there is a hole in the ball part. However, there are no studies on intermittent cutting of thermally-sprayed coatings. In this study, in order to obtain an effective tool material for intermittent cutting of two types of the thermally-sprayed coating AISI 304, the tool wear was investigated experimentally. The results are as follows: (1) In the case of intermittent cutting of Ni-based self-fluxing alloy coating AISI 304, S_i3N₄ ceramics were considered an effective tool material. (2) In the case of intermittent cutting of thermally-sprayed (WC-Cr-Ni) cermet coating AISI 304, the uncoated cBN having the large grain size of cBN and a high content rate was effective for wear resistance.
