怎么样提高刀具的刚性

在不改变刀具材料的同时,怎么样提高刀具的刚性  

1.在满足机床加工要求的情况下,尽量选择直径d大的刀具。由于是4次方的关系,放大的效果会非常明显,例如直径增大一倍,理论上刚性刚性增大至16倍。

2.在满足机床加工要求的情况下,尽量使刀具悬长缩短。

3.在满足多久加工要求情况下,可以考虑改变刀具的材料,即改变弹性模量E,选择弹性模量大的材料,如硬质合金

How to Improve the Rigidity of Tools

How to improve tool rigidity without changing tool material

1. In order to meet the requirements of machine tool processing, try to choose the tool with large diameter D. Because of the relationship of the fourth power, the magnification effect will be very obvious, such as doubling the diameter and theoretically increasing the rigidity to 16 times.

2. In the case of meeting the requirements of machine tool processing, the tool overhang length should be shortened as far as possible.

3. In the case of how long the processing requirements are met, it is possible to consider changing the material of the tool, i.e. changing the elastic modulus E, and selecting materials with large elastic modulus, such as cemented carbide.
