在模具加工中,有时为了考虑加工方便和经济性,我们常常采用一些镶拼结构。镶拼结构在制图上,是很容易办到的,但要在各工种加工中,都满足设计要求,却不容易。我们如不注意某种工种的加工特性,往往会使零件报废或产生一些不必要的损失。 In mold processing, sometimes in order to consider the processing convenience and economy, we often use some mosaic structure. Inlaid mosaic structure in the drawing, it is easy to do, but in all types of processing, are to meet the design requirements, but not easy. If we do not pay attention to the processing characteristics of a certain kind of work, we often make the parts scrapped or generate unnecessary losses.
