Below with CNC Milling (FANUC 0M) the set that machines coordinate department is exemple, demonstrative work measure pursues 2X of master drawing of 1 part drawing, Y to choosing what the graph shows 1 times to be machined to knife method part drawing appearance, after determining position of process designing origin, can undertake by the following method coordinate fastens set machining: 1, preparative work machine tool winds reference point, affirming machine tool coordinate is; 2, semifinished product of the work that hold clip makes through clamping apparatus the spare parts locates, make workpiece locates datum plane and way of machine tool movement agree; 3, measure to the knife with simple and easy measure to knife law, the method is as follows: For φ with the diameter the standard of 10 measures foot of club, a place of strategic importance to the knife, get measured value is X = -437.

726, y = -298.

160, if pursue,2 are shown. Z = -31.

833, if pursue,3 are shown. Value of set of Nextpage4, computation is shown 2 times by the graph, will in front each data that already measured, press set requirement operation. X coordinate set is worth: X= -437.

726+5+0.

1+40= -392.

626mm notes: - 437.

726mm indicates a value for X coordinate; + 5mm is worth to measure marvellous radius; + 0.

1mm is ply of feet of a place of strategic importance; + 40.

0 be in to work location datum plane for process designing origin the distance of X coordinate direction. Graph 3 Z to be worth to set of coordinate of knife method Y: Y= -298.

160+5+0.

1+46.

5= -246.

46mm notes: If the graph is shown 2 times, - 298.

160mm indicates a value for coordinate; + 5mm is worth to measure marvellous radius; + 0.

1mm is ply of feet of a place of strategic importance; + 46.

5 be in to work location datum plane for process designing origin the distance of Y coordinate direction. Z coordinate set is worth: Z= -31.

833-0.

2=-32.

033mm. Note: - 31.

833 indicate a value for coordinate; - 0.

Ply of the 2 feet that it is a place of strategic importance, if pursue,3 are shown. Pass computational eventuate: X -392.

626; Y -246.

460; Z -32.

033. 5, department of set treatment coordinate puts switch below MDI means, entering treatment coordinate is set page. Data-in is: X= -392.

626Y= -246.

460Z= -32.

The 033 X= -392 that express to machine origin setting to be fastened in machine tool coordinate.

626; Y= -246.

460; Z= -32.

Of 033 locally. 6, proofread set to be worth to abecedarian, after the set that had machining origin, answer to proofread set value further, in order to assure the validity of parameter. The particular procedure that proofreads the job is as follows: In set after G54 machines coordinate to fasten, undertake reference point is operated answering a machine tool again, its show indication to be: X +392.

626, y +246.

460, z +32.

033. This specification is in set after G54 machines coordinate to fasten, machine tool origin fastens medium position to be in treatment coordinate: X +392.

626, y +246.

460, z +32.

The 033 set values that this also shows G54 conversely are correct. CNC Milling
