Be like part drawing of the outline inside the graph antrum, use seek an edge implement to the knife, its are detailed move is as follows: (1) X, Y to carry work clamping apparatus outfit to be on machine tool workbench to knife ① , when holding clip, 4 flank of workpiece answer put apart seeks an edge implement measure the place. ② fast shuttle table and main shaft, let seek an edge implement those who measure a head to approach work is left; ③ converts fine tuning operation, let measure a head slowly workpiece of bring into contact with is left, until seek an edge implement glow, coordinate of the machine tool when writing down this fastens medium X coordinate to be worth, be like - 310.

300; ④ is raised seek an edge implement go up to workpiece over the surface, fast shuttle table and main shaft, let measure a head to approach work on the right side of; ⑤ converts fine tuning operation, let measure a head slowly workpiece of bring into contact with is left, until seek an edge implement glow, when writing down this, mechanical coordinate fastens medium X coordinate to be worth, be like - 200.

300; If ⑥ measures head diameter to be 10mm, criterion workpiece length is - 200.

300- (- 310.

300) - 10=100, the X coordinate value in can getting workpiece coordinate to fasten origin W in machine tool coordinate accordingly is - 310.

300+100/2+5= -255.

300; ⑦ can be measured so that workpiece coordinate fastens origin W to tie medium Y coordinate cost in mechanical coordinate with manage. (2) Z to seek an edge to knife ① debus implement, what use treatment main shaft of cutting tool mount; Set of axis of ② general Z implement (or pair of knife piece of fixed height, be the same as below) place go up in the plane on workpiece; Main shaft of ③ sudden shift, let cutting tool end panel stand by Z axis set implement on the surface; ④ converts fine tuning operation, let cutting tool end panel slowly set of axis of Z of bring into contact with implement on the surface, till its pressing with a finger indicates null; Coordinate of the machine tool when ⑤ writes down this fastens medium Z to be worth, be like - 250.

800; ⑥ is like Z axis set implement height is 50mm, criterion W of origin of workpiece coordinate department fastens medium Z coordinate value to be in mechanical coordinate - 250.

800-50- (30-20) =-310.

800. (3) in inputting value of measures X, Y, Z coordinate of machine tool workpiece to fasten memory address (memory of code of general use G54-G59 is right knife parameter) . 4, the note is opposite the knife needs to note the following problem in unit process of cargo bandling: (1) use pair of correct knife tools according to machining a requirement, control pair of knife errors; (2) be opposite in knife process, can raise pair of knife precision through changing fine tuning feed; (3) scrupulous to needing when the knife operation, want to notice mobile way especially, avoid to produce collision risk; (4) must stock as corresponding as the program memory address to knife data, prevent to produce serious consequence because of call error. 2, input and alter the real measure according to cutting tool and position what cutting tool compensation is worth, cutting tool radius compensation cost and cutting tool length compensate a value to input as corresponding as the program memory position. Those who require an attention is, compensatory data validity, symbol validity and validity of data place address go to menace treatment, bring about danger hitting a car or treatment to discard as useless thereby.
