Carry on of summary Lei Ni (RENISHAW) survey head system to knife and work center. Use system of most Xi Menzi A2100 in the light of vertical machining center, combine experience, sum up the Leinishao that develops to its to measure head software demarcate use. Keyword machining center measures the graph in head demarcate to classify label of date TG659 document to pile up a lot of B enterprises to be deployed for equipment to the knife went up Leinishao (RENISHAW) survey head system to knife and work center. Use these to measure a head to be able to reduce the auxiliary time of the machine tool and percent defective, improve product quality and productivity substantially. Measure a head to the knife, can come true to be checked automatically to knife and damaged of automatic cutting tool; Workpiece measures a head, the workpiece before can realizing treatment searchs automatically, the quality inspection in machining a process and control, treatment hind still can realize partial quality to check a function. Although measure the use of the head to have a variety of profit, but because groom a lot of reasons such as inadequacy of insufficient, data, the operation that creates partial manufacturer and technical personnel do not understand measure a head, won't use, measure an use effect not beautiful, even some is unused need not, created huge waste. In be being used actually, have some of equipment manufacturer, although use the machine tool that is company of Lei Ni carry on to measure a head, but the package of the software that measure a head that did not use Leinishao, developed software independently on his system however. About this one part, manufacturer of a few equipment does not have overmuch data, rely on to fumble completely accumulate. Use system of most Xi Menzi A2100 in the light of vertical machining center, combine experience, those who sum up the Leinishao that develops to its to measure head software demarcate use. More than 10 equipment such as the VMC750 vertical machining center that Xin Xin promotes machining center of VMC 1000 vertical and Beijing Electromechanical courtyard then, those who use all is Leinishao MP12 work center measures head and TS27R cutting tool to measure a head. No matter be workpiece,cutting tool measures a head, before be being used for the first time, must undertake demarcate, in order to as a result of,be compensated mechanical (the eccentricity that measures a head, diameter and length) reach electric on (signal is delivered receive, the delay time of numerical control system) the error that cause. One, the demarcate that TS27R cutting tool measures a head to let bougie of sensor of cutting tool bring into contact with, cutting tool measures head unit to should install the positional limits that allows in machine tool motion inside. With the program that will measure cutting tool circular instruction is G68 to install cutting tool dimension and G69 to examine cutting tool dimension respectively. G68 is used at measuring cutting tool length and diameter, numeric record is expressed in cutting tool data or to program is expressed. 1. 3 levels that cutting tool measures a head dictate (1) demarcate measures head length: Do not rotate, foregone and accurate cutting tool or measure a club, demarcate of G68 P5 G90 [Xx] [Yy] [Qn] [Ww] [Dd] (2) measures head diameter: Demarcate of G68 P6 G90 [Qn] [Ww] [Dd] [Rr] [Aa](3) measures head diameter and length: G68 P7 G90 [Xx] [Yy] [Qn] [Ww] [Dd] [Rr] [Aa]2. Parameter explains (include a few parameter that when measuring, use) [Xx] and [Yy] -- of metrical cutting tool center and probe center slant buy is worth [Qn] -- probe strikes a time, 0 delegates two, 1 delegate [Jj] -- give out those who measure small knife is azimuthal [Ww] -- time retreat a distance [Dd] -- distance exceeding Cheng [Rr] -- the radial of cutting tool and probe is removed [Aa] -- the fore-and-aft distance that cutting tool exceeds probe [Zz] -- cutting tool is the shortest patient wear away be worth [, acquiescent value, the length that cutting tool expresses or diameter are updated directly after detecting; N=1, do not update cutting tool to express, show hint only; N=2, not newer cutting tool is expressed [Vv] -- cutting tool diameter is the smallest wear away patiently value [Uu] -- cutting tool diameter is the biggest expand patiently value 3. Specific demarcate measure measures a head to be before demarcate, should look for a foregone accurate cutting tool above all (exemple: L=177 of accurate milling cutter.

7622mm, φ =7.

98mm) , set length, diameter cutting tool the outside and the inside (if set,be a knife, of cutting tool X, Y slant buy is set for 0) . (1) main shaft does not hold a knife, handwheel means shakes main shaft TS27R measures the upper part of the head, note the absolutely coordinate cost of next Z; (2) makes up in main shaft a fine broach, handwheel means shakes main shaft TS27R measures the upper part of the head, in the center of range estimation makes point of a knife aims probe, note the absolutely coordinate cost of next X, Y; (The TS27R parameter that value of absolutely coordinate of the X that records above 3) general, Y, Z writes down parameter of machine tool application in, note Z coordinate cost the FIX-PRB-TRAM in circular parameter to measure head parameter in; (4) sets TS27R parameter in parameter of machine tool application Y slants buy is 30 ～ 40mm; (5) carries out M6T0 G68Q1(to touch probe with main shaft end panel, collide. In carrying out, can try with the hand first pressure touch a head, look whether stop, carry out again next. ) M5 M30(is carried out, the Z of probe calibration face in parameter of program self-correcting loop is worth: FIX-PRB-TRAM. ) Nextpage(6) carries out M6T1 G68 P5 G90 Q0 W50 D2 (measure head height with desired result of standard cutting tool; Cutting tool does not rotate desired result, q delegate strikes a time, 0 for mode, express to be bumped 2 times, 1 express to be bumped 1 times. W is after bumping time shrink distance, d points to distance exceeding Cheng, be in namely after reaching calibration range, if still do not have the probe on collision, the space that takes again at most. Q, W, D is worth the actual condition set according to cutting tool. ) M5M30 (the program ends, the Z of probe calibration face in parameter of program self-correcting loop is worth: FIX-PRB-TRAM. ) (7) carries out M6T1G68 P6 G90 Q0 W20 D4 R20 A5 (measure head diameter with desired result of standard cutting tool, q, W, D is worth the actual condition set according to cutting tool. ) M5 M30 (the program ends, the X of the TOOL_PRB_LOC that parameter registers into the system, Y, Z3 coordinate is worth) (8) carries out M6T1 G68 P7 G90 QO W20 D4 R20 A5 (length and diameter demarcate) M5 M30 4. Note and little experience (1) note: [Rr] , [Aa] parameter is to must want to be defeated; There must be a knife to grow a cost first before measuring a diameter. (2) demarcate little experience: If at hand does not have standard cutting tool, can use the cutting tool that using to replace, the end panel after perhaps mixing diameter of a knife handle compares bright and clean useless knife to turning over outfit clip, also but demarcate. Metrical value is less than real value, be worth the standard make down, new demarcate; Conversely, revise reversely, until accurate. 5. Little experience of the maintenance that measure a head (1)TS27R measures a head to bounce faint. The probe of TS27R used time to grow, press the meeting after falling to bounce occasionally faint, cause probe overtime to call the police. Right now, need the top silk the both sides on main body crust to loosen only, take out the fuse among probe come, fluctuation convert, OK. (What 2)TS27R measures a head to not be in a center to knife position is corrective. After the installation position of TS27R is changed occasionally, perhaps installed a system afresh, press the demarcate of method of demarcate of cutting tool probe above occasionally, when growing to the knife, point of a knife always is absent central position, right now, implement 7 measure first, but carry out not completely, before main shaft falls, press next probe with the hand, make measure is finished ahead of schedule, criterion the central position coordinate of probe is expressed into parameter, carry out from the beginning by afore-mentioned measure again next. 2, the demarcate MP12 that MP12 workpiece measures a head is a nicety is all-around send feeling unit, by probe main body and bougie composition. Installation of probe main body is on machine tool main shaft, when object of bougie bring into contact with and when deflexion is nodded to probe come away, generate collision signal. Detect when control probe when this signal, get a machine tool buy of each position of axle, and save this size cost. G72 dictates the deflection of line of center of main shaft of deviate of measurable bougie center is measured circularly; G73 dictates measurable installation is in circularly the probe inside main shaft is pinpoint dimension, it is ＋ X, - Y of X, ＋ and - the effective bougie size of Y direction (nod to the contact from central line undertake metrical) ; G74 loop instruction sets the length of probe. 1. The standard demarcate of workpiece probe (demarcate of 1) bougie eccentricity: Bore hole measure, demarcate of diameter of ball of probe of G72 G90 [Pp] [Qn] [An](2) : Standard cirque, demarcate of length of bougie of G73 G90 [Pp] [Qn] [An](3) : Foregone height slip gauge, g74 G90 [Zz] [Qn] 2. Parameter explains (include a few parameter that when measuring, use) [Pp] -- the diametical value of the fiducial opening that calibration uses. Without the symbol, blame mode. [Zz] -- below program coordinate department, the absolutely Z coordinate of datum plane. Z word is optional. [Qn] -- probe strikes a time, 0 delegates of N ＝ collide twice, n=1 represents collision. [An] -- N=0 is to delay X/Y axial demarcate; N=1 is 3600 demarcate. 3. Actual in concrete demarcate step (one standard of 1) cirque, put at workbench, find place of the centre of a circle as far as possible with dial gauge or dial gauge, or Huo round hole of one older standard, absolutely coordinate of the X of the centre of a circle below the record and Y is worth; (2) carries out setting of M6T1101 date cutting tool to be probe, the hand shakes inside cirque, make probe coordinate is located in above the center of the record, assure to continue to carry out below probe open circumstance) G72 G90 P79.

1Q0 A0(A0O is to delay X/Y axial demarcate; A1 is 3600 demarcate; Q0 is bumped twice for probe; Q1 is bumped; P79.

1 point to cirque standard diameter) M5M30 (probe center slants buy enters cutting tool to express Xoffset and Yoffset field, measure a few times more, examine commutation of these two values to be in μ level. ) (3) carries out setting of M6T11(11 date cutting tool to be probe, the hand shakes inside cirque, make probe coordinate is located in center as far as possible, assure to continue to carry out below probe open circumstance) G73 G90 P79.

1Q0 A0M5M30 (update a system automatically to register the PROBE_CALIB parameter in + X, - X, + Y, - Y probe compensates a value, measure a few times more, be in till change μ level. ) (if 4) has foregone height gauge block, height the value writes down the TR-AM-SURFACE parameter in circular parameter in, put slip gauge to be on workbench face. (5) carries out length of M6T11(11 date probe first to clear) G74 G90 Z172.

9104Q0(assumes 172.

The 9104 height that are slip gauge) M5 M30 (after be being carried out, probe length feed provides a list; If probe is not accurate, the height that can correct gauge block is worth, new demarcate, until accurate. ) 4. Note and little experience (1) note. Before executive G72 circulates, want first cutting tool the outside and the inside slant buy value is set for 0. Before G73 begins circularly, bougie pointed dimension also wants first to clear. Before executive G74, in must inputting the approximate length of bougie cutting tool to express, this approximation must arrive accurately inside the safe height limits of probe. (2) little experience. If probe length is not accurate, can adopt correction calibration range (slip gauge) high value, repeat executive G74 to come circularly calibration. CNC Milling CNC Machining
