CNC Milling unit process of cargo bandling

Treatment plan shows outline of inside and outside 1 times, compensate instruction process designing with cutting tool radius, cutting tool diameter is 8mm. Graph analysis of 1 treatment plan: Direction of tangent of outline edge circular arc cuts P1 → P2 outside, p3 of → of P2 of direction of tangent of the edge when be being cut, according to judgement, with compensation of radius of left cutting tool. When outline is machined inside, p4 → P5 is entered to cut paragraph, p6 → P4 goes out to cut paragraph, reason uses compensation of radius of right cutting tool. Outline treatment ends outside cancel compensation of radius of left cutting tool, wait for cutting tool to move to be nodded to P4, build radius of right cutting tool to compensate again. Treatment should choose height to grow the square semifinished product that is 240mm for 14mm, edge. The program is as follows: N010G90G92X0 of name of program of O0100; of program explanatory note.

Graph 13 " open a file " the dialog box clicks menu " view / Control Panel switch " , open the MDI clavier of FANUC system, right now the interface is shown 14 times like the graph, graph 14 " CNC Machining emulates a system " the PRGRM key that the interface clicks MDI clavier to go up, CRT is shown 15 times like the graph; In input O01 through MDI clavier, click key again, can input the numerical control program that has edited beforehand, right now CRT is shown 15 times like the graph. Graph how the CRT interface of around of program of 15 inputs numerical control edits through MDI clavier and output numerical control program, at the back numerical control program edits intermediary carry on. 5.

The examination runs orbit to be able to go to switch of knob of the MODE in operating face plate DRYRUN, click the pushbutton START on operation face plate again, can observe the moving contrail of numerical control program, also can pass right now " view " the trends in menu rotates, trends is put shrink, the means such as dynamic translation undertakes to three-dimensional moving contrail all-around trends observes, moving contrail is shown 16 times like the graph. Graph the MODE knob of 16 operations face plate and moving contrail graph 6.

Correct to moving contrail of cutting tool of fiducial, outfit, the procedure that makes clear an input is basic and correct, numerical control program is origin with center of the surface on the spare parts, how to adopt the specification below right fiducial the relation that will build workpiece coordinate department and machine tool coordinate to fasten. Click menu " machine tool / fiducial tool... " , the rigid and columnar fiducial tool that chooses left in fiducial tool dialog box, its diameter is 14mm, if pursue 17; Go to switch of knob of the MODE in operating face plate JOG, click the POS pushbutton of MDI clavier, the control knob that uses rod of the pushbutton JOG on operation face plate and X, Y, Z, move the machine tool roughly the position. Graph 17 fiducial tools pursue 18 pairs of datum mark attack menu " feet of a place of strategic importance is checked / 1mm " , be opposite above all of X axis direction fiducial, will fiducial tool moves to be like the position that the graph shows 19 times, go to the MODE knob switch that operates face plate STEP, the fold knob that goes up through moving moral integrity to make face plate and JOG pushbutton shift are fiducial tool, make clew information dialog box shows " the result that feet of a place of strategic importance checks: Appropriate " , write down next X coordinate with right now medium CRT 113.

503, this is the X coordinate of fiducial tool center, the X coordinate of reason work center is 113.

503-1 (contest feet) - 14/2 (fiducial tool) - 240/2 (workpiece) =-14.

497, the Y coordinate of center of likewise attainable work is - 153.

429. X, y way is standard after be opposite, drive up clicks menu " machine tool / demolish a tool " demolish fiducial tool, click menu " machine tool / choice cutting tool " , choose a diameter to be the flat bottom knife of 8mm, if pursue 20, after packing good cutting tool, the machine tool is shown 21 times like the graph. The Z coordinate that gets the face on workpiece with similar method is - 404.

The impact that setting parameter determines to workpiece and machine tool coordinate are fastened has two kinds of methods, one kind is to adopt G54-G59 set, another kind is to adopt G92 set. What use here is G92 method: Will right fiducial gotten work is in the coordinate data on the machine tool, the origin of workpiece of dimension cipher out that combines workpiece itself is in the position in the machine tool, affirmatory machine tool begins the position when be being machined automatically. The input of cutting tool compensating parameter: Here radius compensates a value to be 4mm. Go to the MODE knob switch that operates face plate EDIT mode, if pursue 22, click menu again " try / Control Panel switch " open MDI face plate, click MENUOFSET pushbutton twice continuously, CRT is shown 23 times like the graph; Ordinal the ← 4X that clicks MDI face plate, .

Pushbutton of T, INPUT, right now CRT is shown 24 times like the graph, finished the input of knife filling data namely. Face plate of 24CRT of graph of 23CRT of graph of graph 22MODE knob 8.

After position of automatic treatment machine tool decides with the knife filling data is inputted, can begin to be machined automatically. Move above all cutting tool reachs work center the position of upper part 100mm, namely (- 14.
