Title: Machining method for holding product weight within standard value by the same machine
Inventor: HASHIMOTO SHIZUAKI
IPC: B23Q17/00
Filed: 1987-03-23
Abstract: PURPOSE:To improve efficiency by regulating a product weight to a specified value through the use of the same machine, by a method wherein the weight of a product, machining of which is wholly completed in a state to partially have a weight-reducible black skin part, is measured within the same machine, and through comparison of the measurement with a standard weight, the cutout size of the black skin part is computed for cutout. CONSTITUTION:Parts A, B, C, E, and F of a piston 1 are wholly machined by means of the numerical control device of a machining center. Since it is not necessary to machine the interior of the piston 1, a black skin part 2 is left formed. After completion of machining, weight is measured by a weight measuring device, e.g. road cells, mounted in the machining center. A measuring weight is compared with a standard weight by means of a comparing means situated in the control device, and when it is heavier than the standard weight, the cutting sizes of a bore D of the piston and a length L are computed in the NC device. It is decided that the D and L are within a standard size and it is decided whether there is a machining margin, and the black skin part 2 is cut to regulate weight to a value which satisfies a standard value. Thus, since weight reduction machining is practicable by using the same machine, efficiency and quality are improved.
