The invention relates to a 
machining method of a T-shaped movable beam irregularly-shaped glass 
machining glass. The T-shaped movable beam irregularly-shaped glass 
machining glass consists of a gantry framework, a fixed platform, a transverse 
stepper / 
servo mechanism, an X-axis screw rod, an X-axis lead rail, a T-shaped longitudinal 
stepper / 
servo mechanism, a Y-axis screw rod, a Y-axis lead rail, an upper 
stepper / 
servo mechanism, a lower stepper / servo mechanism, a Z-axis screw rod, a Z-axis lead rail, a 
grinding head mechanism, a positioning adsorption disc, a control box, a 
polishing grinding wheel, a fine 
grinding heel and a coarse 
grinding wheel; the T-shaped longitudinal stepper / servo mechanism moves along the Y-axis direction of three Y-axis lead rails, and a three-axis 
linked data control system is used for machining the irregularly-shaped glass; and a T-shaped movable beam adopts an integral framework structure, the rigidness of the T-shaped movable beam is good, the stability is good, and the T-shaped movable beam is not deformed when being ground under a large torque, the three lead rails are used as support, so that the T-shaped movable beam is faster to run in the running process, more stable to run and better in synchronous effect, the working efficiency is efficiently improved, and the 
dimensional precision of a final product can be improved.
