【Questions】
I would like to know the correct usage of the end mill for chamfering and V-groove machining
I often use chamfering and V-grooving end mills for machining parts, but I am troubled by frequent chipping of the blade tip. Please tell me the tips for using the tool.
【Answers】
The followings are important points for chamfering and V-groove machining.
・It is necessary to process under the condition settings that consider the maximum depth of cut.
・If the amount of cutting is large, stepwise cutting is recommended.
2. V-groove machining
・V-groove machining is mainly considered when using a normal square end mill and when using a dedicated tool.
(1) When using a normal square end mill
It is a method of cutting the V-groove by tilting the tool or workpiece. If high accuracy is not required for the shape of the bottom of the V-groove, machining with a radius or end mill with corner chamfer is also an option.
(2) When using an end mill for V-groove machining
・When using only the tip of the tool, consider the peripheral speed and set a higher rotational speed.
・If the cutting amount is large, stepwise cutting is recommended.
