WHEN TO USE PRE CONTROL CHART IN MANUFACTURING INDUSTRIES REGARDS ANIL GUPTA

what is pre control chart and when it is to be use. regards anil gupta

Dear Sir 1)What is difference between control chart and pre control chart. 2)which we have to do first regards anil gupta

hello about DPU,DPO,DPMO DPU ( DEFECT PER UNIT)=TOTAL NO. OF DEFECTS OBSERVED /TOTAL NO. OF UNIT PRODUCED. DPO(DEFECT PER UNIT OPPORTUNITY)=DPU/m where m is no. of opportunity DPMO (defect per million oppurtunity)=DPU/m*1000000 for example If m=8 DPU=1 DPO=1/8=0.125 DPMO=DPO/M*1000000=125000 regards anil gupta

dear sir why we are talking about six sigma and not for seven sigma. regards Anil Gupta

Hi Sir what is proto type, Pre launch,production control plan, Regards anil gupta

HI sir I have collect reading 98 numbers for process with diameter 32.3+/-0.2 mm.All data is coming with this tolerence limit .still cp and cpk is coming 0.6 and 0.34 respectively.Can anybody suggest me what interpret this result. How i can get 6 sigma.should i have to increase tolerence limit. what is sub group. regards Anil gupta

What about effectiveness.Can i have more clarification ? Regards Anil Gupta

Hi Leon I am new to this subject.I would like you to refer six sigma for quality and productivity promotion-sung H.PARK. True value is only desired but process mean during one time period is not same with other time due to unavoidable reason.due to this in 6 sigma level process defect is correspond to 3.4 PPM in place of zero. I may be wrong but 6 sigma levle is +/-6 sigma ipo of +/-3sigma.Plz correct me any body if my concept is not wrong. Anil gupta

AND ONE MORE TERM IS THERE THAT IS EFFECTIVENESS.WHICH IS QUALITY RELATED TERM. EFFECTIVENESS=OK QUANTITY/TOTAL QUANTITY ANIL GUPTA

Dear Sir You have told for prevention and detection filling as per 5c.I want to know in preventive control can i use set up approval,work instruction,check chart. 2)if i have applied preventive control ,can i give detection control too. regards anil gupta

I want to apply hypothesis test for hose manufacturing process.Process is curing.In this hose is kept in steam vessel at 144 degree and 90 minutes. My null hypothesis is temp is =144 degree alternate hypothesis is temp <144 degree. I have little understanding bout this test.I want to clear it with example and exercise.

BEFORE FMEA YOU HAVE TO CLEAR OUT PROCESS FLOW AND CHARACTERSITIC MATRIX BETWEEN PROCESS PARAMETER AND DEFECT.
