Really your explaining very well sir thank you, I am referring your videos only since I am quality engineer working in automotive industry. It's really helping us

[@newmechanicalmind8818]

Thank you Ajmal. Keep watching and sharing our videos to your other friends

[@rachurisudheer3250]

Thankyou sir very useful please continue 🙏

[@newmechanicalmind8818]

Keep watching

[@SubbanaickerKanagaraj]

Excellent presentation Hats off

[@newmechanicalmind8818]

Thanks a lot

[@naveenbharathi5288]

Sir,in case 1 and case 2 all the points are comes over the mean and lower the mean...as per our 7 criteria is that ok??

[@naveenbharathi5288]

Because,initially u have said if 7 points over the mean value means some external cause acting on process.

[@newmechanicalmind8818]

Hi Naveen, Part-4 having 4 cases with bell curve only. You can see case-3 & case-4 are upper and lower to mean in part-3. It is applicable for control charts only.

[@arivazhakanravi3881]

This video deserves million views...but. don't worry.

[@newmechanicalmind8818]

Sure.

[@nestdmaic8793]

Thank you sir, and i need latest PPT are you providing the smae for for cost ????

[@newmechanicalmind8818]

Pls send mail to [e-mail]

[@rameshramesh-ip8zo]

This video very useful & interesting thank you sir

[@newmechanicalmind8818]

Most welcome

[@SubbanaickerKanagaraj]

Please make a video on sample sizes AND subgroup size

[@newmechanicalmind8818]

Pls see all videos in SPC series

[@muralis8451]

Super explanation

[@newmechanicalmind8818]

Thank you Murali. Keep watching and sharing our videos to other friends also

[@alwayswithnature2973]

Super sir

[@newmechanicalmind8818]

Thank you

[@arivazhakanravi3881]

Nice bro

[@newmechanicalmind8818]

Thank you bro

[@nagarajanchidhambaram3460]

Plz say what are qa documents and qc documents

[@newmechanicalmind8818]

Hi Nagarajan, your content is noted and will try to upload in future

[@santoshsengunther6974]

Sir, centered means what it tells

[@newmechanicalmind8818]

Hi santosh, it means most of the parts will be produced near to the mean value of the tolerance (see the bell curve and the peak point will be near to the center) .

[@aravindraj7258]

Sir, what is maximum value of cpk

[@newmechanicalmind8818]

Hi Aravind, Cp or Cpk may come more than 20 also (if tolerance is very high) The maximum value of Cpk will be equal to Cp (in that process, process centering will be accurate)

[@dillibabu6402]

X double bar la 10.04value epdi choose panniga

[@newmechanicalmind8818]

Hi Babu, it is assumption only. Pls check LSL & USL in both cases for clear under standing. In both cases LSL & USL will vary. So, same (10.04) value will come above and below the X double bar (centre) line.

[@arunraju5023]

3rd casela process LSL vittu veliya pochu. do process not okthana

[@newmechanicalmind8818]

Process capability ok. But centering only not ok

[@srimoorthi6354]

How do to Runout check shaft?

[@newmechanicalmind8818]

Pls watch our GD&T video

[@SHANKARSHANKAR-pz6jq]

Why Xbar and X double bar taken as same in Pp or Ppk?

[@newmechanicalmind8818]

Because, no sub groups in Pp or Ppk study. 50 or 125 nos will be taken as population for Pp and Ppk study. So average of population is X bar = x double bar (no difference) But for Cp and Cpk study, X bar is average of each sub group. X double bar is average of x bars. It is applicable in Cp & Cpk study only. Because as per sub group size, the sample parts will be taken for SPC inspection periodically.

[@SHANKARSHANKAR-pz6jq]

Sprb bro ...now understand doubt cleared👍

[@MW90s]

I want ppt sir

[@newmechanicalmind8818]

Hi friend, kindly prepare the content by your own for better understanding

[@nagaraj140290]

Sir please share the ppt

[@newmechanicalmind8818]

Hi Mr.Nagaraj, pls prepare your content by copying this video for better understanding

[@sakthivelkaliyappan9277]

Spc format download link add sir

[@newmechanicalmind8818]

It is available in SPC part-5 description

[@SHANKARSHANKAR-pz6jq]

Case 4 la Cpk diagram la X double bar vandhu USL ku aprm thaana varuanum based on ur diagram ..but neenga Mean kulla iruka meri katuringa... Athu mattum konjam clarify pannunga bro

[@newmechanicalmind8818]

Very good Shankar. You are right, x double bar will come after USL only in case 4. I have not mentioned correctly. Thank you for your observation. Now i have corrected my training material. I appreciate your observation.

[@SHANKARSHANKAR-pz6jq]

Tq so much bro....your videos Are so much helpful for me ...Easily understood even minute things also..... Congratulations for this work......We are expecting many things like this to grow up many more peoples....👌👌👏👏👏👏

[@NithishKumar-nh9cy]

If x double bar outside the USL then format should be Xdouble bar -USL,but diagram are USL- Xdouble bar .which one is correct pls clarify sir

[@newmechanicalmind8818]

Hi Nithish kumar, formula wiil not change. The value will come in negative (less than 1) if X double bar is bigger than USL
