    We are losing some of our best Machinists and Welders after their first enlistment due to the lucrative options available in the civilian sector and the lack of opportunities to display their innovative nature in the Marine Corps. An additive and subtractive fabricator in the trenches would serve to be an asset to commanders, because he/she will not be limited by technology or lack of expertise. Both of these specialties present an opportunity to exploit manufacturing capabilities. After all, exploitation

  • The Advantage And Disadvantages Of CNC Machining

    Advantages of Custom CNC Machining There are various businesses that can exploit PC numerical control machine hardware, now and then known as CNC machining. The hardware is utilized to manufacture littler pieces, and in addition to make bigger pieces that are to a great degree exact. The gear that is utilized with CNC machining removes at the undesirable material of the bigger piece keeping in mind the end goal to create a littler part. It is a procedure that advantages both the producer and the

    that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining. Under CNC Machining, machine tools function through numerical control. A computer program is customized

    Difference between CNC & NC machines NC machines In a Numerical Control machine, the program is fed to the machine through magnetic tapes or other such media. The original NC machines were essentially basic machine tools which were modified to have motors for movement along the axes.  CNC machines In a Computer Numerical Controlled machine, the machines are interfaced with computers. This makes them more versatile in the sense that, suppose a change in dimension of a part is required. In a
