Task of technology of calibration of precision of geometry of space of machine tool of 303 numerical control passes spaceflight evaluation

Recently, the bureau of industry of national defence science and technology that spaceflight assumes 303 times (division of former national defence is versed in appoint) metric task ” technology of calibration of precision of geometry of space of numerical control machine tool ” passed a test to evaluate. Current, this task has prepared all checking and accept data, plan to report bureau of work of national defence family to check and accept evaluation. This task uses much general to strap laser interferometer logarithm to accuse diagonal of machine tool body to undertake metrical, use the pace that divide an axis to advance the principle of the law, through compensating the research of the principle to error of space of numerical control machine tool, make up dimensional error to compensate software and interface communication software oneself, compensate a model through built dimensional error, depart gives the 12 errors weight of numerical control machine tool, compensate a watch from error of movable unripe space, pass interface communication software, keep watch of dimensional error compensation into numerical control machine tool, realized the compensation of precision of geometry of space of numerical control machine tool, and compensation effect is apparent. With the pitch error with numerical control at present general machine tool compensation means photograph is compared, this technology achieved a big breakthrough.
