What is the reason for the breaking of cutter while rough milling?
The primary reason for a cutter breaking while rough milling is due to excessive cutting forces. When the cutting forces exceed the strength of the cutter, it will break. This can be caused by a number of factors, such as incorrect cutting parameters, incorrect tool selection, or incorrect workpiece setup.
Incorrect cutting parameters can include too high of a cutting speed, too high of a feed rate, or too deep of a cut. If the cutting speed is too high, the cutting forces will be too great for the cutter to handle, resulting in breakage. The same is true for a feed rate that is too high. If the cut is too deep, the cutter will be overloaded and will break.
Incorrect tool selection can also lead to cutter breakage. If the wrong type of cutter is used for the job, it may not be able to handle the cutting forces. For example, if a high-speed steel cutter is used for a job that requires a carbide cutter, the high-speed steel cutter will not be able to handle the cutting forces and will break.
