IME 146 Questions and Answers Already Graded A All CNC Machines Contain three different components select them: Processing Equipment, Program of Instructions, Machine Control Unit What are the three main ways G & M code can be created for a CNC machine? Manual Programming, Conversational Programming, CAD/CAM Programming CNC milling G & M code is based off the _________ Coordinate System. Cartesian Our Haas CNC machines have a [ ] loop positioning system. The system gets feedback from the [ ] encoder located inside the servo motors on the machine. Closed, Optical The [ ] screw turns rotary motion from the servo motor into linear axis motion and eliminates [ ] in the CNC table drive system. Ball, Backlash TRUE OR FALSE: Fixture offset or work-coordinate systems (WCS) are the same as the world x, y, & z zero position location in the CNC mill machine. False The most common WCS G code is: G54 TRUE OR FALSE: The tool length offset tells the CNC mill the length the tool is sticking out of thespindle. This allows the machine to know where the bottom of the tool is locatedin relation to the Work Coordinate System. True A [ ] code is a preparatory function, it preps the CNC machine for some sort of motion G Fixture Offset G54 Tool Length Offset G43 Rapid Motion G00 Absolute Positioning G90 Clockwise circular interpolation, it cuts in a clockwise arc G02 Linear Interpolation it Cuts in a straight line G01
