Aperture of a flight of stairs kind the craft analysis of the spare parts and citing of numerical control process designing (add CNC Machining working procedure to get stuck) 1, blueprint treatment plan shows hole of a flight of stairs 1 times kind spare parts, material is aluminium alloy, material norms is Ф 50×30mm, among them surplus of semifinished product axial is 5mm, the requirement asks by blueprint treatment completes this part. Graph aperture of 1 a flight of stairs kind spare parts 2, craft analyses surface of this spare parts to be comprised by the surface such as face of cylinder of inside and outside, circular arc, workpiece should undertake in the process of treatment ability completes treatment quite twice holding clip, at the same time the basis is machining aperture kind working procedure is machined according to advanced travel lumen commonly when the spare parts, the treatment that undertakes the machines working procedure principle of the appearance should have opening above all after has the treatment of other side next. 3, operation measure and machine program 1) workpiece holds clip, aperture is added inside the circle locates beyond man-hour, with 3 claw from centering chuck clamp. 2) to the knife, inside pair of knives of aperture boring cutter: Kong Dao is opposite inside before the knife inside aperture has been gotten finish, call place to require cutting tool, be opposite above all Z axis, cutting tool point of a knife is close to the end panel outside workpiece, try the end panel outside cutting workpiece, make good omissions in workpiece next Z0 of the input inside the interface is measured, z axis is finished to the knife, x axis is right knife, along surface of the aperture inside workpiece of Z axis cutting, control of deepness of cutting of edge Z axis is controlled in 10mm, z of cutting tool edge to retreat a knife, main shaft stops turn, measure diameter of the aperture inside workpiece, make good omissions in workpiece measured value of X of the input inside the interface can finish X axis to the knife.
