Abstract

The invention discloses a clearance groove machining method, a 3D substrate product clearance groove machining method and a 3D substrate product. The clearance groove machining method comprises the following steps that the length D1 of the long side of a product to be machined and the width D2 of the short side of the product to be machined are detected, the center point and the center line of the product to be machined are fitted according to the length D1 and the width D2, a CNC rough cutting curve is fitted according to d2, d2 = d1 + sigma, d1 is the distance between the groove long side of an L-shaped clearance groove and the center line, and sigma is tolerance; and the distance d4 between the long side of the L-shaped clearance groove roughly cut according to the rough cutting curve and the long side of the 3D product is detected, the allowance d needing fine trimming is calculated, a CNC fine cutting curve is fitted according to the allowance d, and the L-shaped clearance groove is cut according to the CNC fine cutting curve. According to the clearance groove machining method, the two-time CNC tool connecting position accuracy during CNC machining can be achieved, the tool connecting mark proportion is close to 0%, and the product appearance yield is increased.

Description

technical field [0001] The invention relates to the technical field of electronic product manufacturing, in particular to a method for processing an avoidance groove, a method for processing an avoidance groove for a 3D substrate product, and a 3D substrate product. Background technique [0002] For current electronic products such as mobile phones, the design of the back cover will reserve a space for the camera and other positions, resulting in some areas that need to be cut off after hot bending, and the products after hot bending are processed by secondary CNC. In the process of machining and removing the invalid area, the CNC machining tool entry point and tool exit point will involve two CNC tool connections. [0003] During existing CNC machining, perform CNC programming according to the drawings of the products to be processed, fit the trajectory lines of the primary CNC and the secondary CNC, and adjust the trajectory lines of the two CNCs to the mode of tangent cir...
