V-CUT machining process for V-shaped groove machining of aluminum substrate

Abstract

The invention discloses a V-CUT machining process for V-shaped groove machining of an aluminum substrate. The process includes the following steps that the to-be-machined aluminum substrate is fixed through PINs; the thickness, length and width of the aluminum substrate needing machining are measured, and a to-be-machined residual thickness value, V-cut machining positions and the distance betweentwo adjacent V-shaped grooves are determined; the radius of an upper cutter and the radius of a lower cutter are set; cutter colliding testing is carried out; the cutting depth of the upper cutter and the cutting depth of the lower cutter are determined according to the set residual thickness value; a cutting mode is selected, and the cutting thickness, cutter feeding speed and cutter retreatingspeed of the upper and lower cutters are determined; the rotating speed of upper cutter and lower cutter grinding wheels is determined; V-cut testing is carried out at one position on the selected aluminum substrate, the residual thickness is measured, and cutting is performed; and the surface is cleaned, and residues generated during cutting are removed. According to the process, cutting does notneed to be conducted through a cutting machine, the machining time is saved, the working efficiency is improved, waste generated in the machining process is reduced, and the production cost is reduced.

Description

Technical field [0001] The invention relates to the field of aluminum substrate processing, in particular to a V-CUT processing technique for forming a V-shaped groove of an aluminum substrate. Background technique [0002] The aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Since the aluminum substrate usually needs to be cut according to the customer's needs, the cutting requirements must ensure the accuracy, and the processed groove line is also required to be smooth and free of burrs. The commonly used exterior processing method is to use a CNC milling machine for processing. Different products have different requirements for the processing size of the aluminum substrate. The workload is large, the processing efficiency is very low, and the corner scraps cut from different products each time are relatively large. Many, resulting in a waste of resources. Summary of the invention [0003] Objective of the invention: In view of the a...
