process for machining plates of glass, stone, marble or the like, large size in a job centre in numerical control

摘要

A method for machining a plate (L) of glass, stone, marble, or the like in a workstation (1), comprising the following steps: - pre-arranging on a surface upstream of the workstation (1) the plate (L) to be machined in the correct position prior to entry of the plate into the workstation (1); - feeding the plate (L) set in the correct position to the workstation (1) and causing it to advance longitudinally along said working surface (2) defined by said motor-driven rollers (R), operating said motor-driven rollers (R) until the plate (L) is brought into the initial machining position; - detecting the real position and orientation (PR) of said plate (L) with respect to said working surface (2) by means of a position-detection system; - modifying the program for actuation of the cycle of machining of the plate (L) on the basis of detection of the real position (PR) made in the previous step; and - carrying out machining of the plate (L) by operating the motor means for controlling the movements of the cross member (5), of the carriage (6), and of the operating head (7) on the basis of the modified program for actuation of the machining cycle.
