There are many effects of performing a cutting operation with a dull tool. Note that a dull tool has an increased tip radius. As the tip radius increases (meaning the tool dulls), the cutting force increases due to the fact that the effective rake angle is decreased. In addition, we can see that shallow depths of cut may not be possible because the tool may simply ride over the surface without ...Get Price

During milling operation, the cutting tool is subjected to wear; as a result, the dish angle value decreases, which inﬂuence the more engagement length between workpiece and tool during machining. Thus, the height of residual ridge is increased, which leads to poor surface ﬁnish. Therefore, a cutting tool with dish angle is required to achieve a moderate surface quality and tool life [3,4 ...Get Price

The operation of rough turning is used to remove as much metal as possible in the shortest length of time. Accuracy and surface finish are not important in this operation. Therefore, max depth of .030 inch and a .020 to .030 inch feed is recommended. Workpiece is generally rough turned to within about .030 inch of the finished size in a few cuts as possible.Get Price
