Cemented Carbide Tool Life

Relationship between posterior horn size and cemented carbide tool life (Electrical parts of face machining)

Cemented carbide tool life means a new cemented carbide cutting tools from the beginning put into use until the total cutting time up to the end-of-life, which includes multiple regrinding (number of regrinding said n) time, so cemented carbide tool life equal to the tool the durability multiplied by the (n +1).

Workpiece material：ADC-4F Parts diagram
Processing machinery: self - made special machine tools cemented carbide tool life
Tools:39-3（TH10）
Conditions:
rotation speed570r/min
Cutting speed270m/min
Feed rate0.15mm/r
Cutting depth3mm

Results: previous practice of cutting the anterior horn of the standards tools get bigger, a little while you will find the cutting edge becomes dull, the surface roughness of the machined surface. According to the size of the posterior horn and cemented carbide tool life relationship, if not only the anterior horn made ​​bigger, increase the posterior horn, the problem is solved.

BUE
Turning tool behind and the workpiece material contaction makes BUE

Summary: the greater the rake angle, cutting resistance is smaller; the smaller wedge angle will be reduced, but the strength of the cutting edge. Anterior horn size affects the cutting resistance changes also affect its cutting heat generation. This angle becomes larger cutting heat reduced, increase becomes small cutting heat. The aluminum casting, etc. are particularly vulnerable to the influence of the cutting heat, in this case, in order not to produce BUE and occurrence of adhesion, according to the size of the rear corner and tool life relationship, can choose a very fast cutting speeds, or increase large front corner and rear corner, so that you can greatly reduce the probability of occurrence of phenomena such as fever and bonding.
