Overview: What is CNC Machining?
CNC (Computer Numerical Control) machining is an automated manufacturing process that uses high-speed cutting tools to precisely shape metal or plastic stock materials. Common CNC machines include milling machines, lathes, and routers with 3-axis to 5-axis capabilities. The cutting approach varies - the workpiece may be stationary while the tool moves, the tool may be stationary while the workpiece moves, or both may move simultaneously.
Skilled machinists program the tool paths based on CAD models of the final part geometry. CNC machining offers high precision and repeatability, making it suitable for custom parts across industries like aerospace, medical, robotics, and electronics. UTM provides CNC machining services quoting over 40 materials from aluminum to engineered plastics like PEEK and Teflon. The computer control enables automated, efficient material removal through processes like milling, drilling, and turning.
