Ques:- What is the formula to calculate machine and process capability?

Asked In :- Deluxe entertainment services India, Visionet Systems, Smart Cube India, TriSys, Maruti Techlabs, Unistring Tech Solutions, EY GDS, AB InBev, Akij, LGB,

Right Answer:
The formula to calculate machine capability (Cp) is:

Cp = (USL - LSL) / (6 * σ)

And for process capability (Cpk):

Cpk = min[(USL - μ) / (3 * σ), (μ - LSL) / (3 * σ)]

Where:
- USL = Upper Specification Limit
- LSL = Lower Specification Limit
- μ = Mean of the process
- σ = Standard deviation of the process
