Gantry-type adjustable measuring machine machining method

The invention discloses a gantry-type adjustable measuring machine machining method. The method includes steps of 1, analyzing finite elements; 2, mounting a Y-axis aluminum plate; 3, adjusting the locating datum of a base of a measuring machine and locking the base; 4, sequentially machining locating faces of the Y-axis aluminum plate by feeding once; 5, mounting online a Y-axis double rail, and mounting online a triangular beam and an X-axis aluminum plate; 6, sequentially machining locating faces of the X-axis aluminum plate by feeding once ; 7, mounting online an X-axis double rail, and mounting online a Z-axis module mounting plate; 8, sequentially machining locating faces of the Z-axis aluminum plate by feeding once; 9, performing entire online natural aging treatment; 10, mounting online an X-axis grating ruler, an X-axis magnetic plate, a Y-axis grating ruler, a Y-axis magnetic plate, a Z-axis module and the like; 11, demounting various special fixtures, and finishing machining. The locating faces of the measuring machine are machined by clamping and locating once and feeding once, mounting accumulated errors can be avoided effectively, and operating efficiency is high.
