Direction of reference axis of numerical control machine tool decides measure and methodological example really

Reference axis direction decides methodological measure really: (1) the athletic way of coordinate of Z coordinate Z is by what hand decision of place of cutting dynamic main shaft, namely parallel is Z coordinate namely at the reference axis of main shaft axes, of Z coordinate to the way that leaves work for cutting tool. If there are a few main shafts on the machine tool, choose perpendicular the main shaft direction that places plane at workpiece outfit is Z coordinate direction; If main shaft can swing, choose perpendicular the direction that places plane at workpiece outfit is Z coordinate direction; If the machine tool does not have main shaft, choose perpendicular the direction that places plane at workpiece outfit is Z coordinate direction. The graph shows the Z coordinate that is numerical control lathe 1 times. Graph the coordinate of lathe of 1 numerical control is (2) parallel of coordinate of X coordinate X places plane at the outfit of workpiece, it is commonly inside horizontal. When the direction of affirmatory X axis, want to consider two kinds of cases: 1) if workpiece does whirligig, criterion the square that cutting tool leaves the direction of workpiece to be X coordinate to. 2) if cutting tool does whirligig, divide for two kinds of circumstances: When Z coordinate level, when observer looks to workpiece along cutter spindle, + X movement way is pointed to right; When Z coordinate is perpendicular, when observer faces cutter spindle to look to pillar, + X movement way is pointed to right. Graph 1.

7 show the X coordinate that is numerical control lathe. (3) Y coordinate is in the square of coordinate of affirmatory X, Z backward, can use the way according to X and Z coordinate, according to right hand rectangular coordinates the department determines the direction of Y coordinate. The graph shows the Y coordinate that is numerical control lathe 1 times. Graph the coordinate of milling machine of vertical of 2 numerical control is fastened 2.

Citing exemple: The structure of milling machine of numerical control vertical that the graph shows the basis 2 times pursues, try linear coordinate of affirmatory X, Y, Z. (1) Z coordinate: Parallel at main shaft, cutting tool is from the way that opens work. (2) X coordinate: Z coordinate is perpendicular, and cutting tool rotates, face cutter spindle to look to pillar direction so, it is right. (3) Y coordinate: After coordinate of Z, X is affirmatory, with right hand rectangular coordinates the department decides. CNC Milling
