CNC Milling Machine Replacement of hard or rigid automation by Flexible automation by developing and using CNC has made a great break through since mid seventies in the field of machine tools’ control. The advantageous characteristics of CNC machine tools over conventional ones are: flexibility in automation change-over (product) time, effort and cost are much less less or no jigs and fixtures are needed complex geometry can be easily machined high product quality and its consistency optimum working condition is possible lesser breakdown and maintenance requirement The versatility of CNC milling machine has been further enhanced by developing what is called Machining Centre. Single Purpose & Automatic Milling Machines: Used for short thread milling like in mass production of small bolts and screws.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
