profile grinding for moulds

Fabrication of small aspheric moulds using single point

Determination of radius of a cylindrical wheel. In profile grinding of concave surface, the diameter of the wheel will influence the interference between the wheel and the workpiece. As shown in Fig. 2 (a), a small cylindrical wheel moves along the line OP3 to It is found that ductile domain grinding of ceramic moulds to achieve the required contour profile of 6.7 μm PV accuracy and a surface roughness Ra of less than The mechanisms of high-efficiency grinding for micro/meso

Fabrication of small aspheric moulds using single point

In arc grinding shown in Figs. 1(a) and 1(b) the wheel arc is in contact with the workpiece, so the profile accuracy of the arc grinding wheel has significant effect on the profile accuracy of the ground surface. Also, the contact point is varied (moving along the arc) during arc grinding, so it is difficult to accurately estimateThen grinding point distribution on the ball-end wheel is calculated, and the grinding characteristics, grinding speed and maximum undeformed chip thickness, are investigated. Finally, a complex structural component can be ground without interference, and surface roughness and profile accuracy are improved to 40.2 nm and 0.399 μm, Fabrication of small aspheric moulds using single point inclined
