cnc machine tools lecture notes Computer Numeric Control (CNC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium (computer command . A box junction is an area in the centre of a junction, usually at a busy crossroads or T-junction, where the road is marked with a yellow criss-crossed box. They are there as traffic control measures, to prevent gridlock at junctions.

It indicates where to start, how to move and when to stop. Group G-Code function 00 G54 WORK COORDINATE SYSTEM 00 G59The CNC program can be written, stored, and executed directly at the CNC machine. 3. Any portion of an entered CNC program can be played back and edited at will. Tool motions can be electronically displayed upon playback. 4. Many different CNC programs can be stored in the MCU. 5. Several CNC machines can be linked together to a main computer.Machines Using CNC Early machine tools were designed so that the operator was standing in front of the machine while operating the controls. This design is no longer necessary, since in CNC the operator no longer controls the machine tool movements. On conventional machine tools, only about 20 percent of the time was spent remov-ing material.The material in this manual was checked and deemed to be accurate. The entire risk as to its accuracy and quality is with the reader. In no event shall NexGen Manufacturing Systems, Inc. be liable for direct, indirect, or consequential damages resulting from any
