CNC- Computer Numeric Control - IIT Kanpur
Computer Numeric Control TA202A 2017-18(2nd) Semester Prof. J. Ramkumar Department of Mechanical Engineering IIT Kanpur Computer Numeric Control A system in which actions are controlled by the direct insertion of numerical data at some point. The system must automatically interpret at least some portion of this data. Computer Numerical Control (CNC) Machine Advantages and Disadvantages of CNC. Advantages: High Repeatability and Precision Aircraft parts. Volume of production is very high. Complex contours/surfaces can be easily machined.
It uses a stepper motor to rotate the lead screw. A stepper motor is driven by series of electrical pulses generated by MCU. For each pulse the motor rotates a fraction of revolution called Step Angle, it is given by Where, n s ... N6 G00 Z5 D5 M3 S500 X20 Y90 . N8 G01 Z-2 F50 . N10 G02 X60 Y50 I0 J-40 .
