cutability

The material cutability is described and evaluated with a target system and the fuzzy comprehensive evaluation method.

试图用指标体系来描述和料切削加工性。

What is obtained with the forging waste heat normalizing and controlled cooling technique is the coarse stable structure in a 20CrMnTi gear, but its cutability is good.

余热正火和常规正火处理后，再经同工艺进行渗碳、淬火和回火处理，试验证明：其渗层和心织、晶粒度及机械性能均相同。
