DLP-MECH-T112: Word document CAD/CAM turning and milling Measuring systems CNC-CAM- machines

The text explains the importance of measuring systems in CNC (Computer Numerical Control) and CAM (Computer-Aided Manufacturing) machines, highlighting the use of coordinate systems, zero points, and the procedures for setting these points to ensure precise machining. CNC machines use absolute and relative coordinate systems to define tool and workpiece positions. Key zero points include the machine zero point (the machine’s origin), the workpiece zero point (the reference on the workpiece), and the tool zero point (the reference on the tool). Setting zero points involves homing the machine, referencing with a tool or probe, and establishing the machine zero based on the reference location. The process often includes “running into” reference points, where the tool or probe contacts a known point to record positions accurately. Properly setting these zero points is essential for maintaining precision and quality in machining operations.
