A glass cutting line includes automatic remnant storage and retrieval including cutting table with integrated squaring stop and y-break breaking bar facilitating sub-plate cutting. The cutting table is configured for sub-plate cutting mode which provides the ability to cut portions of a stock sheet and release the cut portion in the form of a remnant and or individual workpieces to breakout before the entire sheet is finished scoring without the sub-plate leaving the cutting table.

A method for forming an initiation defect in a glass substrate to facilitate separating the glass substrate into a plurality of substrates is provided. The method includes providing the glass substrate and contacting a broad surface of the glass substrate with an abrasive surface thereby forming a field of initiation defects in the broad surface of the glass substrate. The field of initiation defects has a width of at least about three millimetres between outermost initiation defects. At least one initiation defect is heated with a laser source. The at least one initiation defect is cooled with a cooling fluid such that a crack initiates from the at least one initiation defect, the crack extending through a thickness of the glass substrate and propagating across the glass substrate to separate the glass substrate into the plurality of substrates.

The present application discloses a cutting method and a cutting machine table for cutting a substrate, where the cutting method includes following steps: cutting a large substrate to be cut to obtain a finished substrate falling on a second cutting machine table; after the cutting, driving the second cutting machine table according to a preset parameter to enable a driving-away height difference to be formed between the second cutting machine table and the first cutting machine table; driving the second cutting machine table away from the first cutting machine table; and resetting the second cutting machine table to an initial state.
