To horizontal CNC Milling, answer respectively when main shaft and workbench 0 hind, workbench centre of turning circle will be in with machine tool reference point the umbriferous coincide inside horizontal. The coordinate value that right now workbench centre of turning circle carries the nodical distance of the face to be coordinate of machine tool of XC, YC; to the front of main shaft axes and main shaft is next indication is right now 0, after main shaft or workbench are mobile, the X that shows below department of machine tool coordinate, Y is worth even if workbench centre of turning circle is worth relative to the coordinate of machine tool reference point, main shaft center is worth relative to the Z coordinate of machine tool origin. Be versed in in what decide, mobile main shaft and workbench, the workpiece origin that makes choose is in X to, Y to with coincide of main shaft axes, in Z to with coincide of face of main shaft front, namely knife dot and workpiece origin coincide, at this moment workbench centre of turning circle is worth in the coordinate in department of machine tool coordinate, be versed in for this namely when origin of workpiece coordinate department ties medium coordinate cost in machine tool coordinate. this value the input slants to 0 o'clock buy register is corresponding the position, can using G54-G59 instruction to build workpiece coordinate is. If use G92 instruction to build workpiece coordinate department, criterion knife the node of the end panel before the dot also gives priority to axial axes and main shaft, the position of rest of main shaft and workbench is in at 0 o'clock, input slanted at 0 o'clock value of coordinate of the X after the negative worth of the value of buy register dictates for G92 namely, Y, Z, spot position needs to be examined easily, facilitate the treatment precision; that improves work is in then usually, what to the knife the dot uses all is the origin that workpiece coordinate fastens. The dot that change a knife is surely really in process of CNC Milling treatment hard to avoid encounters much knife to machine, no matter be to change knife or hand automatically to move,change a knife, need to determine the position of the dot that change a knife. Accordingly, it is very important that the precision when changing a knife to nod much to CNC Milling knife to machine certainly masters. Usually, the dot that change a knife is with allowing to be touched cutting tool, clamping apparatus and workpiece are a principle certainly, the dot that change a knife is outside the outline that processes work, take the safe space with have certain.
