1.Manualcorrection
1‐1.Introduction
InVPanel,youcanmakecorrectionsofthemachine.Performcorrectionsifyouwanttopreciselyadjustthe
accuracy.
RefertoVPanelGuideformoreinformation.
NOTE: CorrectionsinVPaneldoesnotguaranteeanycuttingaccuracy.
CoordinatesandoriginofDWX‐50
DirectionofeachaxisisasfollowswithDWX‐50.XYZoriginwillbesetatthecenteroftheclamp.
AandBoriginsarethepointwheretheclampisleveled.
Manualcorrection
Acorrectionwindowcomesupwhenyouclick[Manualcorrection].
YoucanmakethreecorrectionsinVPanel.
NOTE:Ifyoutick[Clearthesevalueswhenexecutingrotaryaxiscorrection],allthecorrectionvalueswill
beclearedwhenyouexecute[Correctrotaryaxis]inVPanel.
Allthemanualcorrectionvalueswillbeignoredwhenyouexecute[Correctrotaryaxis].

1.Distance(correctionofdistanceintheXYZdirection)
Itwouldbeidealforthemodelingmachineifitsmovingdistanceisexactlythesameasyouexpectedbutit
doesnotalwaysfitwithoutanyerror.
CorrectionofdistanceintheXYZdirectionworksforcompensatingtheerrorbetweenthevalueyouexpected
andactualvalue.
EachDWX‐50hasitsinternalcorrectionvalueatthefactory(Factoryautocorrection)forerrorcompensation
sothatmovingdistancewillfitasyouexpected.
InVPanel,youcanmakecorrectionofdistancemanually.
Youcanfindthetwocorrectionvaluesonthesystemreportas"LENGTHCORRECTION".
Function
Thisisusedwhenanobjectisbigger/smallerincertaindirection.
Availableoffsetrange:99.500%to100.500%,inincrementsof0.001%
Default:100%
2.Aaxisbackside(inversioncorrectionofAaxis)
Intwo‐surafecutting,itisimportantthattheAaxisturns(A=0/A=180)withoutanyerror.
InversioncorrectionofAaxisworksforcompensatingtheerror.
Function
ThisisusedwhenthethicknessinZdirectionisdifferentbetweentheleftandtheright.
Availableoffsetrange:‐1.00degreeto1.00degree,inincrementsof0.01degree
Default:0.00degree
Ifaoffsetvalueisbiggerthan100%,
thesizebecomesbigger.
Ifaoffsetvalueissmallerthan100%,
thesizebecomessmaller.
Ifyouinput100.1%inY‐axis,thelengthinY‐axiswillbelongerin100.1%.
Incasetheoriginallengthis10.00mm,itwillbe10.01mm.

3.Originpoint(correctionoftheorigin)
WhenDWX‐50performscuttingdisplacementcouldoccurinthecuttingresult,becausethemachineperforms
two‐surfacecuttingusingtherotaryaxis(Aaxis).
Correctionoforigincompensatestheerrorbyshiftingtheoriginposition.
Function
ThisisusedwhenthereisadisplacementinYdirection,orthethicknessinZdirectionisthicker/thinner
thanyouexpected.
Thefunctionvariesdependingonthedirection.
Availableoffsetrange:‐1.00mmto1.00mm,inincrementsof0.01mm
Default:0mm
Ifyouinputapositiveoffsetvalue,
thethicknessattherightwillbethinner,
theleftwillbethicker.
Ifyouinput(+)0.01degree,
therightmostthicknesswillbethinnerby0.008mm,
theleftmostthicknesswillbethickerby0.008mm.

CorrectionofXorigin
ItisnotnecessarytomakeacorrectionforXoriginbasically.
Cuttinglocationdoesnotchangeintwo‐surface(A=0/A=180)cuttting,thereforethedisplacementmay
notoccur.
CorrectionofYorigin
InYaxisdirection,cuttinglocationisinvertedintwosurfacecutting,thereforethedisplacementcould
occur.
CorrectionofYorigincanminimizethedisplacementbetweenthefirstsurfaceandthesecondsurface.

CorrectionofZorigin
IfZoriginisdifferentbetweentheonethesoftwarecalculatesandtheoneactuallyset,itmakesthethickness
oftheobjectthicker/thinner.
CorrectionofZorigincompensatestheerrorinthickness.

1‐2.HowtofindadisplacementinZ‐axis
Itisimportanttomakeanappropriatecorrectiondependingonthesituationoftheerror.
Makesurethesituationshownbelowtomakeacorrectioninanappropriateway.
Case1:CorrectionofdistanceintheZdirectionisrequired
Theamountoferrorincreasesinproportiontothethickness.
Case2:InversioncorrectionoftheAaxisisrequired
TheerrorreversesacrosstheAaxis.
Case3:CorrectionoftheZoriginisrequired
Theamountoferrorisalwaysthesameregardlessoftheposition
