Vertical CNC machining is a computer-controlled process that uses vertically oriented power tools to perform operations such as milling and drilling. CNC machines are guided by CAD programs and require minimal operator intervention, producing high levels of accuracy. The process is suitable for a variety of operations and offers benefits such as consistency and minimal intervention requirements.
Vertical CNC machining is any machining operation with a computer-controlled power tool that has a vertically oriented tool tip. These operations typically include milling and drilling and are performed on machines that rely on computer numerical control (CNC) computer programs to complete a given cycle. Vertical CNC machining can be used to complete jobs such as planing, slot and groove cutting, profile contouring, and drilling. Machines typically feature multi-dimensional worktables that move both the cutting head and the workpiece to complete any job. CNC machines are driven by computer aided design (CAD) programs that control most, if not all, functions, require minimal operator intervention, and produce extreme levels of accuracy.
Vertical power tools are machines with vertically oriented tool tips. The most common of these are the drill press and router. Drill presses generally feature static tool bit laterally and workpiece positioning and rely on vertical movement of the entire press head to complete drilling operations. Milling machines differ in that the tool tip and workpiece can be driven past each other during milling. Both types of machining can be operated manually, semi-automatically or fully automated as in the case of CNC machines.
The tool and workpiece mechanisms on CNC machines are remotely controlled and guided by a computer system that uses CAD files to move them during machining operations. Vertical CNC machining jobs usually begin with the creation of a detailed drawing of the part produced from one of the CAD programs. This drawing contains all relevant information about the part, such as dimensions and profiles, and serves as the basis for a program that includes all the information the machine needs to complete the job. This program includes information such as start and end points, different tools used, tool speeds, machining sequences and of course all the physical dimensions of the part.
Once on the vertical CNC machining computer, the stock is loaded and machining begins. During the cutting operation, the computer directs the machine mechanisms to move both the tool tip and the workpiece to complete the job exactly as intended in the program. The vertical CNC machining process is suitable for completing a wide variety of operations including contour milling, face milling, slot and keyway cutting, pattern drilling, reaming and reaming. The obvious benefits of vertical CNC machining include accuracy and consistency over long runs of parts and minimal operator intervention requirements.
