When numerical control process designing, to describe the campaign of the machine tool, simplify the method of to program and the interchangeability that assure record data, the coordinate department of numerical control machine tool and athletic way already all were standardized, ISO and protocol of my national capital named standard. Pass the study of this one part, can master the concept that coordinate of department of department of machine tool coordinate, process designing coordinate, treatment fastens, have start work actually the ability that installs a machine tool to machine coordinate to fasten. Department of machine tool coordinate decides measure and method really: 1 machine tool is relative to athletic regulation on the machine tool, we think workpiece is dormant from beginning to end, and cutting tool is motion. Such process designing personnel are in take no account of the workpiece on the machine tool and cutting tool below the circumstance of particular movement, can pursue according to the spare parts appearance, determine the treatment course of the machine tool. The correlation of reference axis of the X in the department of coordinate of formulary level machine tool that coordinate of 2 machine tools fastens, Y, Z uses the right hand Cartesian rectangular coordinates is a decision. On numerical control machine tool, the movement of the machine tool is by numerical control device comes pilot, the figuration that goes up to decide numerical control machine tool moves and assist movement, must determine the direction of the displacement of the motion on the machine tool and motion first, this comes true with respect to need through coordinate department, this coordinate fastens what be weighed to be department of machine tool coordinate. For example on milling machine, the fore-and-aft motion of organic bed, transverse motion and hang down to motion, if pursue,1 is shown. Should use department of machine tool coordinate to describe in CNC Machining. Graph the correlation of reference axis of the X in department of coordinate of machine tool of standard of 1 vertical CNC Milling, Y, Z uses the right hand Cartesian rectangular coordinates is a decision: (1) the thumb that reachs the right hand, forefinger and middle finger, and each other is 90 ° . Criterion thumb represents X coordinate, forefinger represents Y coordinate, middle finger represents Z coordinate. (2) of thumb point to the square that is X coordinate to, of forefinger point to the square that is Y coordinate to, of middle finger point to the square that is Z coordinate to. (3) around the whirl that coordinate of X, Y, Z rotates coordinate uses A, B, C to express respectively, according to formula of right hand helix, of thumb those who point to axis of the random in be coordinate of X, Y, Z to, criterion the 4 direction of rotation that point to are the others namely rotate of coordinate A, B, C to, see a picture 2. Graph the square that the direction that the provision that 2 rectangular coordinates are 3 movement way increases cutting tool and work space is each reference axis namely to, the square that if the graph is shown 3 times,moves for on numerical control lathe two to. Graph the direction that 3 machine tools move CNC Milling CNC Machining
