Be based on the MV of MasterCAM9

Daterate (110, 150, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400) ? 9600 if transmit an order with MasterCAM directly,express, its baud rate is 9600. The most complex in Pst file is variable use. MasterCAMV6.

Its postposition handled the 0 version before to use variable partly, and V7.

0 above already used variable to write Pst program in great quantities in version program, accordingly file of development, custom-built Pst must understand its variable definition and use. Variable and general component is 6 groups in Pst: Compensation and motion and positional variable, cutting tool variable, deflection variable, fixed loop variable, miscellaneous a parameter variable and string and target variable. Pair of variable need before use variable first " the format is described " again " the format is appointed " , if be in format of loop of treatment of aperture of custom-built SINUMERIK810D system new appeared the variable such as Paaa, need to define beforehand in Pst: Paaa#ForceZaxisoutputazabs=zabsazinc=zincifabsinc=zero, *azabs, ! Zincelse, *azinc, ! Zabs combines Pst file setting, mp file undertakes reading take and be handlinged to Nci file, accordingly, know the format of Nci file and Pst file and structure, it is the foundation that postposition processing designs. 3.

The characteristic MV-610 machining center of 2MV-610 machining center and NC process designing is the small-sized vertical machining center that company of Taiwan Europe horse produces, knife library capacity is 20 knives, use disk type to trade knife unit automatically, knife library needs to control shift only, with blade holder encode means picks a knife, the system codes to every blade holder in knife library, when changing a knife, the cutting tool that gets on main shaft first in the dot that change a knife gets off, put in former blade holder, reassume gives the knife number that the program assigns, choose knife movement and the course that the movement that change a knife is an edge add. But 810D system still asks the program that pick a knife puts in two block with the program that change a knife: After electrify of NaT12Na+1M06 this machining center, must return reference point first, ability entertains other movement, later but need not return reference point every time. But this machine tool is half closed-loop control, next motion on machine tool main shaft and workbench motion lie besides operating ring, undertake as the abidance that machines a process, the floating conference of machine tool main shaft and workbench produces an error to accumulate, and machine tool main shaft must return the ability after appointing the position to change a knife again. Because this is necessary,reference point is returned after every working procedure is finished. Reference point postposition is returned to handle an order in the work out, still need to consider craft sex issue, z axis should return reference point first again XY axis winds reference point at the same time, touch a knife in order to avoid. 810D system answers reference point to dictate code is G74, output block is: The numerical control system that place of N_G74Z1=0N_G74X1=0Y1=0 this machining center provides is the SINUMERIK810D of company of German Xi Menzi, SINUMERIK810D/840D is current one of main numerical control systems, its process designing dictates with the system such as FANUC photograph comparing has bigger difference: Outside dictating except G00-G99, M00-M99, among them code of partial G, M did not assign a function, still added the 3 digit word such as G110-G112, G820-G829, G500-G599 denotive G instruction; In addition, the English word of abbreviate, like TRANS/ATRANS (at 0 o'clock translation) , ROT/AROT (coordinate rotates) , MIRROR/AMIRROR (mirror) , NORM/KNOT (be close to and exit outline) , CYCLE (Kong Jia is versed in the standard circulates) the process designing statement with wait to also be become significant, make SINUMERIK810D system program more complex. 3.

The design of special postposition transaction file is opposite 3MV-610 machining center it is quite complex that custom-built postposition handles specific numerical control system and machine tool, on the foundation of the circumstance such as requirement of register of code of M of control of limits of rotate speed of speed of feed of the distance that must know origin of manual of machine tool user, machine tool and each reference axis first, each axis, main shaft, machine tool and process designing manual, machine tool and G code, address and its format, basic to 6 when define beforehand of the Pst file in MasterCAM module undertakes designing, again custom-built composition is basic the user of module defines aftertreatment module oneself, be revised then or the variable that redefine user defines aftertreatment module oneself. 810D system file begins to begin to have with FANUC system file very big different, include set program name, show the comment such as process designing date, time; The output format of 810D system is: %_N_ZK3_MPF;PROGRAMNAME – ZK3;DATE=DD-MM-YY-3-10-05TIME=HH:MM-16:5The postposition that defines beforehand in 0N100G71N102G0G17G40G90pst handles module to be: Psof#Staroffilefornon-zerotoolnumber " %_N_ " , *progno, "_MPF " , e " ; PROGRAMNAME- " , program, e " ; DATE=DD-MM-YY- " , date, "TIME=HH: MM- " , time, epbld, n, *smetric, epbld, n, *sgcode, *sgplane, "G40 " , *sgabsinc, e and loop of treatment of FANUC system bore have very big different, the output format of 810D system is: CYCLE81 (RTP, RFP, SDIS, DP, DTB) ; The postposition that defines beforehand in Pst handles module to be: Pdrlcommonb#CannedDrillCyclecommoncalln, *feedn, "MCALL " , "" , *sgdrill, "(" , initht, ", " , prdrlout, ", " , "5.

The last word uses the special postposition that designs according to afore-mentioned methods to process the NC code that program place generates, can handle outline completely, inside groove, curved surface and the cutting tool method that all sorts of aperture machine file, do not need to make processing 2 times artificially, the MV-610 that can deserving to have SINUMERIK810D system applies directly on machining center, machine the spare parts of all sorts of types; Improved efficiency of MasterCAM9 process designing greatly thereby, implement CNC Machining automation. To the numerical control system of other, also can consult this method undertakes custom-built. CNC Milling
