通常圆柱螺旋铣刀具有直径(D)、螺旋角(ω)、刀齿法向前角(γ_(?))、齿深(h)等参数,这里统称其为设计参数,一般在设计图纸中已给出。使用单角度铣刀加工螺旋沟槽时,其所使用的刀具直径(d)、安装角(β)、错位量(S)、吃刀深度(H)等参数可称为工艺参数(见附图,图中O—工件中心,O_1—刀具中心,S′—机床横进给方向上的错位量S′=S/cosβ)。 Usually cylindrical helical cutter diameter (D), helix angle (ω), the rake angle (γ_ (?)), Tooth depth (h) and other parameters, referred to here as the design parameters, generally in the design drawings Given. The parameters such as tool diameter (d), mounting angle (β), misalignment (S), depth of cut (H) used in machining helical grooves using a single-angle milling cutter can be referred to as process parameters , O-workpiece center in the drawing, O_1-tool center, S’- misalignment S ’= S / cosβ in the infeed direction of the machine tool.
