How to Master Metal Cutting with A.Bhattacharya's Book: Theory and Practice


the material removed during a turning operation is the removed metal. this removed metal is also known as the chip. chip breakage or chipping is the breaking off of small particles of material, usually metal, as a result of the cutting action. it is different from wear, which is the gradual wearing down of the cutting edge by continued use. chip formation and chipping can affect a turning operation in several ways. the first way is that the chip may break off, causing the material to be scattered around the work piece or tool, causing damage to other parts of the machine or tools and wasting material. the second way is that the chip may become trapped under the cutting edge, possibly causing the cutting edge to break off, resulting in the loss of the tool itself. the third way is that the chip may be formed in such a way that it cannot be removed from the work piece without completely ruining the operation. the fourth way is that chip may be formed in such a way that it can be removed from the work piece without completely ruining the operation. the fifth way is that the chip can be formed in such a way that it can be removed without causing damage to the work piece or the cutting tool. the sixth way is that the chip can be formed in such a way that it can be removed without causing damage to other parts of the machine, tool or work piece.




Metal Cutting Theory And Practice By A.bhattacharya.pdf



metal cutting is the process of machining metal, usually through the use of a cutting tool that removes metal from the work piece, thereby shaping and forming the metal into a particular shape and size. the process is accomplished by holding the metal against the cutting tool, rotating the tool, and advancing the tool into the work piece. the cutting action is caused by the relative movement of the tool and the work piece. the metal removed by the cutting action is the chip. the chip is generally removed by a device known as the chip breaker. the cutting tool and the chip breaker may be considered together as the cutting tool and cutting tool head. the chip can be removed from the work piece either by advancing the cutting tool into the work piece, or by rotating the work piece. the chip breaker typically is a square-shaped steel plate with a hole in it.
