四、合理切削用量的制定在刀具材料、刀具几何角度确定之后,还要制定合理的切削用量。实际上,三者之间互有影响,在选择刀具材料和刀具几何角度时,也应当考虑切削用量这个因素。确定合理的切削用量,涉及一些理论问题和实际问题。必须弄清切削用量三要素对刀具耐用度的影响关系,并对生产成本和加工工时等作周密的调查。兹分述如下。1.t-υ关系的驼峰性众所周知,当用硬质合金刀具加工钢料
Fourth, a reasonable amount of cutting in the development of the tool material, tool geometry point of view, but also to develop a reasonable amount of cutting. In fact, the impact of the three, in the choice of tool material and tool geometry point of view, should also consider the amount of cutting this factor. Determine a reasonable amount of cutting, involving some theoretical and practical issues. It is necessary to understand the impact of the three factors of cutting dosage on the durability of the tool and make a thorough investigation on the production costs and processing man-hours. It is divided as follows. 1.t-υ hump relationship is well known, when using carbide cutting tool steel
