METHOD OF MULTIPASS MECHANICAL TREATMENT Russian patent published in 1994 - IPC

FIELD: metal treatment by cutting. SUBSTANCE: given in known methods traditional order of actions, under which after each pass piece is measured and correction value is formed by comparison of measured and given values, requires optimal position of alignment value in field of clearance and correction value has additional error of measurement, calculation and motion, to be taken into account during calculation of alignment value. Determination of alignment value and of correction value is significantly simplified by change of location of alignment value and admission of correction value as constant for all passes, depended only on value of clearance for size, specification of SPID system and error of measuring device. and does not depends on measured and given sizes. As a result of it first limiting size is taken as alignment value and correction value equals to production clearance less errors of measurement and motion. EFFECT: method of multipass mechanical treatment is used in metal treatment by cutting. 2 dwg
