Description

Technical Field

[0001] The invention relates to the technical field of overflow brick processing, and in particular to a control process for precise processing of an overflow brick work surface. Background Art

[0002] The main glass forming methods are divided into float method and overflow method. The float method is to flatten the glass liquid on the surface of the molten tin pool, and then thin it to form a flat glass sheet. One side of the float glass sheet is in contact with the air, and the other side is in contact with the tin liquid. The surface quality of the surface in contact with the air is better, while the surface quality of the surface in contact with the tin is worse. The overflow method allows the glass liquid to be flattened into two pieces through the two side walls of the overflow brick. The two pieces of glass are in contact with the air on one side and the overflow brick on the other side. Then the two pieces of glass are combined into one piece of glass at the tip of the overflow brick. The side in contact with the overflow brick is combined together. The final glass sheet has two sides in contact with the air. The surface quality of the glass is better than that of float glass. The key forming component of the overflow method is the overflow brick. The overflow brick allows the glass liquid to overflow into two pieces first, and then the two pieces of glass are combined into one to form a complete piece of glass. The quality of the overflow brick processing directly determines the quality of the glass produced by the overflow method.

[0003] The general overflow brick work surface processing process is to find the position first, and then perform normal processing. Due to the measurement error when finding the position, the different amplitudes of swing when the tool rotates at high speed, and the shape error introduced by the wear of the tool, there is a large error between the final processing size and the expected processing size, and the error can reach several millimeters. Summary of the invention

[0015] S9: Compensate the workpiece coordinate measurement error to the selected workpiece coordinate, compensate the radius error caused by tool measurement, tool vibration, and tool wear to the tool radius, and compile a formal machining program;

[0016] S10: Through the various data in the implementation process and the final processing accuracy error, it can be concluded that the processing error is within 1 wire.

[0017] Preferably, the dimensions of the workpiece coordinates in various directions are measured before trial cutting, and the processing model is drawn in the programming software.

[0042] S10: Through the various data in the implementation process and the final processing accuracy error, it can be concluded that the processing error is within 1 wire, and the 1 wire is the length unit of mechanical processing.

[0043] Example 2, reference Figure 1-2 This embodiment is optimized based on the embodiment 1 and includes the following steps:
