现就我厂用小直径铣刀加工大直径圆弧的铣切方法介绍如下(见图1):一、立铣头应扳角度β的计算sinβ=(d+(d~2-4h(D-h))~(1/2))/2(D-h)式中 d——铣刀直径 D——工件圆弧直径 h——工件被加工的圆弧弦高二、盘铣刀直径d的最小极限值的选用 Now I plant with a small diameter cutter large diameter arc milling method described below (see Figure 1): First, the milling head angle β should be calculated sinβ = (d + (d ~ 2-4h (Dh) ) ~ (1/2)) / 2 (Dh) Where d - milling cutter diameter D - diameter of the workpiece arc h - the workpiece is processed arc chord height II, the minimum milling cutter diameter d Use
