On X6 2W milling machine profile of milling of milling cutter of figuration of the tine that use a shovel is like the work that the graph shows 1 times, workpiece material is 45 steel, the γ F ＝ of milling cutter 100, α F ＝ 100, try design high-speed steel to shovel tine figuration milling cutter. Part of workpiece profile curve allows an error to be person 0.

1mm, angle allows an error to be person 15 ′ pursue 1 one, dimension of structure of milling cutter of the figuration that shovel tine decides according to workpiece profile is calculated the structural dimension of figuration milling cutter, computational measure sees a table 1, express 1 to strengthen the structural measure of milling cutter of bottom land figuration.
