Hi community, I’m opening this discussion to talk about how to manage the capability studies in sewing processes.
For some processes like clothes industry, it is not a big issue but in case of some processes like airbags for cars, life jackets,etc it become critical to fill the specifications and assure the capability of the processes.
The question is, with the bellow values and information, is it possible to calculate a capability study?
Specification: 32 to 38 stitches in 100 mm
Machine: CNC sewing (it have very little variation)
Result of the measurement of 30 pieces:
35 35 35 35 35 35 35 35 35 35 36 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35
Cp=?
Cpk=?
