四、工艺参数操作人员在操作磨床时存在着许多变量。在这些变量中间进行选择可以得到工作参数的许多组合,这些组合可以制造出满足零件图规范的工件来。规范规定了尺寸公差和表面粗糙度数值。为了加工出高质量要求的表面,对零件功能关系极大的高应力区或高应力表面提出更严格的规范。选择低应力磨削的具体参数应通过四个不同步骤进行:1)了解需要低应力磨削的零件表面的工作要求;2)确定达到低应力磨削目的所必需的各种试验;3)选取每一参数的具体数值;4)对照要求检验选择的可行性。第一步是了解应用的目标,要求或规范。必 Fourth, process parameters Operators operating grinder, there are many variables. Choosing among these variables gives you many combinations of operating parameters that make it possible to produce workpieces that meet part drawing specifications. The specification specifies dimensional tolerances and surface roughness values. In order to produce high-quality surfaces, more stringent specifications are imposed on high-stress areas or high-stress surfaces where the function of the part is extremely large. The specific parameters for selecting low stress grinding should be carried out in four different steps: 1) understanding the work requirements of the surface of the part requiring low stress grinding; 2) determining the various tests necessary to achieve the purpose of low stress grinding; 3) selecting The specific value of each parameter; 4) control requirements to test the feasibility of choice. The first step is to understand the goals, requirements, or specifications of the application. must
