31. A subsidiary was Santa Ana Metal Stamping, which Brock set up to produce stamped metal parts using numerical control machinery. 32. While there, he completed his dissertation, " The Process for Quantitative Handling of Positioning Errors of Numerical Control Machines ." 33. The forge contains a blacksmith workshop, a couple of welding machines and CNC ( computerized numerical control ) mills as well. 34. In 1993, Parsons ( but not Stulen ) was inducted into the National Inventors Hall of Fame for inventing numerical control . 35. A sluggish recovery and the surging yen didn't deter sales of numerical control devices, the components that go into machine tools. 36. Numerical control machine tools could mill the device out of a metal blank, also working from an Autocad or similar design.37. An alternative could be CNC ( computer numerical control ) .-- talk ) 15 : 38, 24 October 2007 ( UTC) 38. The laser optics and CNC ( computer numerical control ) are used to direct the material or the laser beam generated. 39. A popular application for this type of robot is a computer numerical control machine ( CNC machine ) and 3D printing. 40. Becoming more popular is the use of a CNC wood router, which implements the advantages of CNC ( Computer Numerical Control ).
