电加热器加工会出现多处区域加工不到的现象

 电加热器精加工后出现多处区域加工不到的现象,而最终采取在精加工后进行一次光整加工或依靠后期大量的人工修磨来保证加工精度,大大降低了加工效率。出现此现象的原因是由于切削刀具在制造过程中存在一定钝圆半径。

After the finishing of electric heater, there are many areas that can not be processed. Finally, after finishing or finishing, a large amount of manual grinding is needed to ensure the machining accuracy and greatly reduce the processing efficiency. The reason for this phenomenon is that the cutting tool has a certain radius of blunt circle in the manufacturing process.
由于电加热器精加工切削刃钝圆半径的存在,使得材料在加工中存在最小切削厚度,当加工中切削厚度小于材料最小切削厚度时,刀具与工件之间不能进行正常的切削,而以犁耕和滑擦为主,造成加工质量及尺寸精度难以保证。

Because the electric heater finishing cutting edge radius, the material has the minimum cutting thickness in the processing, when the processing of cutting material thickness is less than the minimum cutting thickness, not between the tool and the workpiece with normal cutting, plowing and scratching, made the processing quality and dimensional accuracy is difficult to guarantee.

电加热器精加工以往学者早已发现该问题,并进行了大量研究,学者FILIZ 等认为,当切削加工中未变形切屑厚度与切削刃钝圆半径为同一数量级时,将造成大负前角切削,导致工件表面产生毛刺。
Electric heater for finishing the previous scholars have found the problem, and a lot of research, scholars such as FILIZ that, when machining the undeformed chip thickness and the cutting edge radius for the same magnitude, will cause a large negative rake angle cutting, resulting in surface burrs.
