The function of word and word

Character and code character are to use the organization, a few signs that control or show data, accord with of operation of word of exactly the amount, letter, punctuation mark, maths. Numerical control system can accept binary information only, must change character into byte of 8BIT field complex so, with " 0 " and " 1 " assorted code will convey. On international use code of two kinds of standards extensively: (1) code of standard of ISO international Organization for Standardization (2) code of standard of association of industry of electron of EIA United States the encode method of these two kinds of standards is different, on machine tool of contemporary most numerical control these two kinds of code can be used. 2.

The word is in CNC Machining program, the word is to point to a series of character that form by the regulation, store as an information unit, deliver and operate. The word is by an English letter and subsequently a certain number of composition of decimal numeral word. This English letter calls address symbol. Be like: "X2500 " it is a word, x is address accord with, number " 2500 " the content in be an address. 3.

The function of the word comprises each word of block to have its specific function meaning, it is the standard with system of FANUC-0M numerical control gives priority to those who will introduce below, in real work, ask manual of system of numerical control of comply with machine tool to use each functional words. (1) word of order of order of 　 of N of ordinal size word calls block date or block serial number again. First what arrange serial number to be located in block, by N of ordinal size word and follow-up number composition. N of ordinal size word is address accord with, follow-up number is average 1 ～ 4 integral. The suitable serial number in CNC Machining is the name of block actually, carry out with the program early or late order has nothing to do. Numerical control system is not to press the order of ordinal date to execute an order, the permutation when be being written according to block however is chased orderly paragraph carry out. Arrange the action of serial number: The corrector to the program and retrieve revise; Regard a condition as the target that change direction, serve as namely turn to object program paragraph name. The block that has ordinal number can undertake revert is operated, this is to show treatment is OK from the program among begin, or return a program to interrupt place begin. Use a method commonly: When process designing the first block coronal with N10, later with interval the 10 methods that increase by degrees set ordinal date, such, if need,block is inserted between N10 and N20 when debugging a program when, can use N11, N12. (2) the address accord with that prepares 　 of functional word G to prepare functional word is G, call G function or G statement again, it is a kind of statement that is used at establishing pattern of machine tool or control system work. Follow-up number is average 1 ～ 3 integral. Meaning of G function word expresses (FANUC-0M system) Normal LINE-HEIGHT of word of 12pt" Align=center>G function: Normal Align=center> meaning: Normal Align=center>G function: Normal Align=center> meaning: 12pt" Align=center>G00 Normal Align=center> sudden shift nods fixed position Normal Align=center>G70 Normal LINE-HEIGHT of loop of 12pt" Align=center> finish machining: 12pt" Align=center>G01 Normal LINE-HEIGHT of 12pt" Align=center> linear interpolation: 12pt" Align=center>G71 Normal Align=center> is thick cut circular Normal Align=center>G02 Normal LINE-HEIGHT of interpolation of 12pt" Align=center> clockwise arc: 12pt" Align=center>G72 Normal Align=center> end panel is thick cut circular Normal Align=center>G03 Normal LINE-HEIGHT of interpolation of 12pt" Align=center> anticlockwise circular arc: 12pt" Align=center>G73 Normal Align=center> closes cutting loop Normal Align=center>G04 Normal Align=center> suspends Normal Align=center>G74 Normal Align=center> deep aperture gets circular Normal Align=center>G17 Normal Align=center>XY plane chooses Normal Align=center>G75 Normal LINE-HEIGHT of loop of grooving of 12pt" Align=center> external diameter: 12pt" Align=center>G18 Normal Align=center>ZX plane chooses Normal Align=center>G76 Normal LINE-HEIGHT of loop of cutting of 12pt" Align=center> compound whorl: 12pt" Align=center>G19 Normal Align=center>YZ plane chooses Normal Align=center>G80 Normal Align=center> cancel secures circular Normal Align=center>G32 Normal LINE-HEIGHT of cutting of 12pt" Align=center> whorl: 12pt" Align=center>G81 Normal Align=center> nods bore loop Normal Align=center>G40 Normal Align=center> cutting tool cancels Normal Align=center>G90 Normal LINE-HEIGHT of process designing of 12pt" Align=center> absolute value: 12pt" Align=center>G41 Normal Align=center> cutting tool compensates -- left Normal Align=center>G91 Normal LINE-HEIGHT of process designing of 12pt" Align=center> increment size: 12pt" Align=center>G42 Normal Align=center> cutting tool compensates -- right Normal Align=center>G92 Normal LINE-HEIGHT of loop of cutting of 12pt" Align=center> whorl: 12pt" Align=center>G43 Normal Align=center> cutting tool compensates -- Normal Align=center>G94 Normal LINE-HEIGHT of 12pt" Align=center> minutely feed: 12pt" Align=center>G44 Normal Align=center> cutting tool compensates -- negative Normal Align=center>G95 Normal Align=center> every turn feed Normal Align=center>G49 Normal Align=center> cutting tool cancels Normal Align=center>G96 Normal Align=center> constant fast control Normal Align=center>G50 Normal Align=center> main shaft is highest rotate speed restricts Normal Align=center>G97 Normal Align=center> constant fast cancel Normal LINE-HEIGHT of 12pt" Align=center>G54 ～ : 12pt" Align=center> machines coordinate to fasten set Normal Align=center>G98 Normal Align=center> returns initiative and planar Normal Align=center>G65 Normal LINE-HEIGHT of macroinstruction of 12pt" Align=center> user: 12pt" Align=center>G99 Normal Align=center> returns R plane (3) the coordinate position that word of size word size uses at deciding motion of the cutting tool on the machine tool is terminal. The first group of X, y, z, u, v, w, p, q, r is used at determining terminal linear coordinate size; The 2nd group of A, b, c, d, e is used at determining terminal angle coordinate size; The 3rd group of I, j, k is used at determining the size of coordinate of the centre of a circle of circular arc outline. (4) the address accord with of word of function of feed of 　 of F of feed function word is F, call F function or F statement again, use at assigning the feed rate of cutting. (5) the address accord with of word of function of rotate speed of main shaft of 　 of S of word of function of main shaft rotate speed is S, call S function or S statement again, use at appointing main shaft rotate speed. (6) the address accord with of word of function of cutting tool of 　 of T of word of cutting tool function is T, call T function or T statement again, the place when be being used at appointing treatment uses the number of cutting tool. (7) the address accord with of word of auxiliary function of 　 of M of auxiliary function word is M, follow-up number is average 1 ～ 3 integral, call M function or M statement again, with the switch movement that assists device at appointing numerical control machine tool. Meaning of M function word expresses (FANUC-0M system) Normal LINE-HEIGHT of word of Center" Align=center>M function: 12pt; TEXT-ALIGN: Normal Align=center> meaning: 12pt; TEXT-ALIGN: Center" Align=center>M00 Normal Align=center> program stops Normal Align=center>M01 Normal Align=center> plans to stop Normal Align=center>M02 Normal Align=center> program stops Normal Align=center>M03 Normal Align=center> main shaft rotates Normal Align=center>M04 Normal Align=center> main shaft is anticlockwise rotate Normal Align=center>M05 Normal Align=center> main shaft rotates stop Normal Align=center>M06 Normal Align=center> changes knife Normal Align=center>M07 Normal Align=center>2 date opens Normal Align=center>M08 Normal Align=center>1 date opens Normal Align=center>M09 Normal Align=center> cooling fluid closes Normal Align=center>M30 Normal Align=center> program stops and return begin to be in Normal Align=center>M98 Normal Align=center> calls subprogram Normal Align=center>M99 Normal Align=center> returns a subprogram CNC Milling CNC Machining
