Abstract

The invention discloses a method for positioning a shell part in a horizontal machining center and a machining method. The clamping position of the shell part on a machine tool workbench after the workbench rotates is determined, the shell part is machined, the method comprises the steps that the shell part is fixed at any position of the machine tool workbench, a user macro program of a numericalcontrol system is compiled, the user macro program of the numerical control system is input into a numerical control system of a machine tool, and automatic offset of the origin of coordinates duringmultidirectional machining is realized. According to the method for positioning the shell part, the coordinates of the original point of a workpiece coordinate system are obtained through automatic conversion of the macro program, the debugging time can be shortened, theoretical calculation has no error, the debugging rejection rate can be reduced, the cost is saved, and automatic offset of the coordinate original point during multidirectional machining can be achieved without clamping a workpiece datum point to a rotation center of the workbench.

Description

technical field [0001] The invention relates to the field of numerically controlled horizontal machining, in particular to a positioning method and a machining method for shell parts in a horizontal machining center. Background technique [0002] For shell parts, features in multiple orientations can be processed in one clamping on the horizontal machining center, that is, features in all directions except the top surface and bottom surface can be processed to avoid errors caused by multiple clamping. However, for horizontal plus multi-directional machining, in order to be intuitive and convenient for programming and calculation, the method of manually measuring and establishing the workpiece coordinate system at different machining angles is usually used at present. Before processing, level the fixture first, then find out the reference point on the fixture or the workpiece, and then calculate the zero offset value of the workpiece coordinate system corresponding to the B-a...
