N5190 G3 X-26.7 Y136.305 I4.083 J4.096 N5192 X-26.661 Y136.304 I0. J5.783 verry small change in Y as above is causing the problem ? Would you please modify MasterCAM of output format? Or, you may try parameter N5008#5 from 0 to 1 to check any improvement. N05008 P 00000000 à P 00100000 This is because Fanuc controller has calculated the command of path. However, the two points are too closed for G02/G03 moving which is like a straight line. Fanuc will think to run path with big arc. Please refer it. OTHER REF.: see some solutions provided by machine tool supplier

Hi!, Thanks . I changed the control setting : Minimum arc radius = 0.02 & break arcs at quodrants . You can see the line where arc is taking longer path than a shortest path. Only when there is a small diffrence in X or y postion in circular path N5188 G2 X-30.783 Y137.992 I22.175 J-90.224 N5190 G3 X-26.7 Y136.305 I4.083 J4.096 N5192 X-26.661 Y136.304 I0. J5.783 N5194 X-25.882 Y136.378 I-.172 J5.922 I do have few queries : why do we need minimum radius as : 0.005 or evn 0.1 when we knwo that we cannot machine lower than cutter radius In some case default max radius is given 200 mm : It should be maximum so as to allow lrger arcs i. 9999mm or more Tolarance in surface toolpath where this error is geneating i.e Surface finish contour : 0.001 is default value : we changed later to 0.01 What is the setting required in machine controller . Any machine parameter ? Problem is due to machine taking larger portion of arc at this location see image attached. Thanking you for your suggestions ! regards

Update Cplane and Tplane when changing Gview
NITIN W replied to Dan_AKA_ROY's topic in Industrial Forum
WHETHER IT IS REQUIRED TO SET THE JOB IN THE VIEW WE ARE SUPPOSE TO MACHINE IN 5 AXIS ???? FOR LHS FACE MACHINING WE NEED TO MAKE CPLNE/ TPLANE IN LHS ???? NITIN -
Kindly check if I am doing correct setting or not ??? its a 5 axis machine with table/table config. ( Rotary a and b attachment) Seimens 840 D I wish to machine an impeller clampled on A axis Table , Whether I will need to orient the job in LHS view to do machining . Is it OK ?? kindly suggest. i.e. in Plane dilog box Working co-ordiate syst = Left side view Tool Plane = left hand side view Comp./ Construction plane = left hand side view kindly check Regards Nitin

Hello FRIENDS ! this macine is 5 axis machine . Its a horizontal machine It has rotary axis A in spindle i.e. at A = 0 its a horizontal machine and at A = -90 its a VMC. its bse rotary table " B" is on x axis table . what should be primary and secondary axis and its vect and dir ???? I have considerd as below Kindly let me know..if I am wrong. mtype : 1 #Machine type (Define base and rotation plane below) #0 = Table/Table #1 = Tilt Head/Table #2 = Head/Head #3 = Nutator Table/Table #4 = Nutator Tilt Head/Table #5 = Nutator Head/Head head_is_sec : 1 #Set with mtype 1 and 4 to indicate head is on secondary #Primary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis must be the XY plane rotaxis1 = vecz #Zero rotdir1 = vecx #Direction #Secondary axis angle description (in machine base terms) #With nutating (mtype 3-5) the nutating axis and this plane normal #are aligned to calculate the secondary angle rotaxis2 = vecz #Zero rotdir2 = vecy #Direction Secondly #Axis shift shft_misc_r : 0 #Read the axis shifts from the misc. reals #### 0 #Part programmed where machine zero location is WCS origin- #Applied to spindle direction, independent of RA #Table/Table - #Offset of tables to secondary axis relative to machine base. #Tilt Head/Table - Head/Head - #Part programmed at machine zero location- #Offset in head based on secondary axis relative to machine base. #Normally use the tool length for the offset in the tool direction saxisx : -500 #The axis offset direction? ### 0 saxisy : 0 #The axis offset direction? saxisz : 378.325 #The axis offset direction? when machine spindle is at centre of rot. of B x axis reading is 500 . and spidle axis fulcrum length i.e. dist from rotation axis to adapter fitting point. = 378.325 whether I am correct???

I got stuck up for one Dialog 3 post. I want tool offcet in every z motion I could get it in all other blocks except plin. can you suggest... regards Nitin plz see below plin #prv_z = z if rapflag = 1, pnewrapid compflag = 1 #n, pccomp @ no # #if prv_rapflag = 1, !rapflag, ex #n, sgcode, z, *tloffno, pfr, "ZZZZZ", e if z <> nextz, [ n, sgcode, x, y, pfr, pcan, e #n, sgcode, z, pfr, e#*tloffno ] else, [ n,sgcode, x, y,pfr, pcan, e if z = nextz, [ n, z, *tloffno, pfr, pcan, e ] else, [ ] ] n, pccomp

HI... TOOL OFFCET IN ALL Z MOVES . FOR T01 it should be D+01 and for FOR T02 it should be D+02 like wise. I COULD MANAGE IT IN PTLCHNG,PRAPID, BUT IN PLIN ITS GIVING ME TROUBLE CAN ANY ONE HELP ME OUT... plin #prv_z = z if rapflag = 1, pnewrapid compflag = 1 #n, pccomp @ no # if prv_rapflag = 1, !rapflag, ex #n, sgcode, z, *tloffno, pfr, "ZZZZZ", e if z <> nextz, [ n, sgcode, x, y, pfr, pcan, e #n, sgcode, z, pfr, e#*tloffno ] else, [ n,sgcode, x, y, pfr, pcan, e n, z , e if z = z ,*tloffno, e # @ whole line is added ] n, pccomp BASICALY I AM NOT GETTING OFFCET IN Z NEGATIVE I.E. WITH DEPTH OF CUT WITH THIS POST BLOCK THANKING YOU....NITIN
