Mechanics of Metal Cutting - Manufacturing Technology
During machining, long and continuous chips formed at high cutting speed will affect the machining process.
NEED AND TYPES OF CHIP BREAKERS During machining, long and continuous chips formed at high cutting speed will affect the machining process. It will spoil the tool, work and machine. These chips are hard, sharp, and hot. It will be difficult to remove the metal and also it is dangerous. Chip breakers are used to break the chips into small pieces for easy removal, safety and to prevent damaging the machine and work. It is very important to provide chip breakers in automatic machines and machines which are running at high speed. The various types of chip breakers provided on the cutting tool are shown in Figure 1.15. The different types of chip breakers used on a cutting tool are: (i) Step type (ii) Groove type and (iii) Clamp type In the step type, a step is ground on the tool face behind the cutting edge. This step will break the chip. In the groove type, a groove on the tool face behind the cutting edge will break the chip. In the clamp type, a thin chip breaker is clamped or screwed on the face of the tool.
