1. The 5-degree bevel setting on the wire EDM machine primarily controls the tool's back rake angle to 5 degrees. During machining, the back rake angle is typically 5 degrees when machining with a new tool.
2. When cutting the back of the die with the upper groove cutter, the molybdenum wire must not touch the cutting tool during processing. The angle of the cutting tool should be greater than the angle of the diamond sheet being processed. This is mainly to avoid damaging the sheet during processing. The part being processed is primarily the cutting tool body, i.e., the part that supports the diamond sheet. The purpose is to prevent the cutting tool from hitting other parts when processing wood flooring. It also facilitates chip removal during processing.
3. Summary of Tool Relief: Tool relief refers to the portion of the groove cutter that is retracted. During machining, the molybdenum wire must be adjusted to be vertical. The method for adjusting the molybdenum wire to be vertical is to bring the fixture close to the molybdenum wire, so that the entire molybdenum wire is in contact with the surface of the fixture.
4. Summary of Angled Cutting Boards: An angled cutting board refers to the side edge of the cutting board. Its purpose is to prevent contact with other parts during the processing of wood flooring.
5. Details to pay attention to during the machining process: 1) After each machining operation, check the XY scale values at the time of stopping. This helps in judging the machining quality when machining the next tooth and allows for timely adjustments if problems arise. 2) When installing the workpiece, wipe the surface of the cutting tool and the fixture to ensure the tool's height is consistent.
