如图1中所示的零件,直径1136毫米,高225毫米,外形为曲面方程Y=0.00125X～4,表面粗糙度要求为Ra=1.6μm,材料为不锈钢。加工这样的零件,一般都需要大型数控机床。在没有大型数控机床的情况下,可在立车上用百分表找零手动仿形加工。靠模板是根据曲面体(线)方程Y=0.00125X～4由数控线切割机切割厚度为4毫米的钢板制成,并用0号砂布砂光。使用时,如图1所示,先将靠模板固定在侧刀架上,再用百分表校正靠模板基面K与横
Parts shown in Figure 1, the diameter of 1136 mm, 225 mm high, the shape of the surface equation Y = 0.00125X ~ 4, the surface roughness of Ra = 1.6μm, the material is stainless steel. Processing such parts, generally require large CNC machine tools. In the absence of large-scale CNC machine tools in the car can be used on the car with a dial gauge to find the zero hand-profile processing. The template is based on the surface body (line) equation Y = 0.00125X ~ 4 by CNC cutting machine to cut the thickness of 4 mm steel plate, and with 0 sandpaper sanding. When used, as shown in Figure 1, first by the template fixed on the side of the turret, and then use the dial indicator to correct by the template base K and horizontal
