VMC machining refers to machining operations that utilize vertical machining centers (VMCs), which, as the name suggests, have vertically oriented machine tools. These machines are primarily utilized to turn raw blocks of metal, such as aluminum or steel, into machined components. They can be used to perform a variety of machining operations, including, but not limited to, the following: cutting, drilling, tapping, countersinking, chamfering, carving, and engraving. This versatility, combined with their relatively low cost, has made them a highly common machine shop tool.
