Adding time on Setup Sheets

[Anonymous]

Is there a way to add time on the setup sheet for a toolpath? We have been finding that it has been taking a little longer for some toolpaths. So I know that CAD time isn't going to ever equal real time but is there a way that I can add time?

Cutting time, numeric value in minutes.

NCProgram:

${ncprogram.Statistics.nTotalTime}

Toolpath:

${stoolpath.nCuttingTime}

Time is very inaccurate.

I understand that but higher ups are asking for more realistic cycle times

[GlennM.MCAM]

I don't think there is a fix that will apply for every machine. Slowing down in corners, tool change time, ... are variables that powermill don't calculate with the toolpath time. I guess you should test some things out for a period of time and see how much percent deviation you have from the calculated time.

We have been keeping track of the times and we have been finding that it has been around 1.5 times the original. Is there any way to multiple the cycle times as well as the total NC program time by 1.5?

heres what I use. change the 2.9 to 1.5  it outputs in hours

BOOL err = entity_exists ('ncprogram','')

IF NOT $err {
    STRING ncProg = INPUT ENTITY NCPROGRAM "Select NC Program"
    ACTIVATE NCPROGRAM $ncProg
}

STRING LIST tpNames = extract(entity('ncprogram','').nctoolpath, 'Name')
INT i = 0
REAL ncTime = 0

GRAPHICS LOCK
FOREACH name IN $tpNames {
    STRING str = $tpNames[i]
    ACTIVATE TOOLPATH $str
    DEACTIVATE TOOLPATH
    ACTIVATE TOOLPATH $str
    REAL nonCutting = $toolpath.Statistics.LeadsAndLinks.Times.Others + $toolpath.Statistics.LeadsAndLinks.Times.Plunge + $toolpath.Statistics.LeadsAndLinks.Times.Ramp + $toolpath.Statistics.LeadsAndLinks.Times.Rapid
    REAL cutting = $toolpath.Statistics.CuttingMoves.Times.Arcs + $toolpath.Statistics.CuttingMoves.Times.Linear
    REAL tpTime = (($nonCutting + $cutting) * 2.9) / 60

    $i = $i + 1
    $ncTime = $ncTime + $tpTime
}
GRAPHICS UNLOCK

MESSAGE INFO time_to_string($ncTime, "H")

Thanks, would I put this into my summary html file to get the setup sheet cycle time to be adjusted?

Hi all

you can use this {Statistics.TotalTime *1.5} for each toolpath or ${time_to_string(project.ntotaltime*1.5,"M")} for all project

In Setup Sheet you can use:

{time_to_string(1.5*project.nTotalTime,"M")}                                 for total time

{time_to_string(1.5*stoolpath.nTotalTime, 'M')}                             for NC program time
