Unlock the secrets to a streamlined manufacturing process with our host, Matthew Woodford, as he breaks down the essential techniques to achieve an Overall Equipment Efficiency (OEE) of 85% or higher. Learn how to produce consistently good parts by mastering Statistical Process Control (SPC) and process capability analysis. Matthew dives deep into the importance of capability indices like Cp/Cpk and Pp/Ppk, providing the knowledge needed to control variation and ensure a stable process.
Matthew also sheds light on the critical steps of Advanced Product Quality Planning (APQP) and the necessity of conducting run-at-rate capability trials for new equipment. Discover why specifying quality expectations during the tender process can save you from costly delays and setbacks. You'll gain invaluable insights into achieving a minimum PPK standard of 1.67 and meeting the higher standards demanded for critical characteristics. This episode is a goldmine for anyone looking to enhance their manufacturing process and meet customer demands efficiently.
The formulas referred to in this episode are
Voice of the Customer (VOC) / Voice of the Process = Cp, Pp
Standard Deviation | P(%) | Ppm | Cp
± 3,75 S | 99,982 | 178 | 1,25
± 4 S | 99,994 | 64 | 1,33
± 4,5 S | 99,9994 | 6 | 1,50
± 5 S | 99,99994 | 0,6 | 1,67
± 6 S | 99,9999998 | 0,002 | 2.0
- A Cp of 1.33 shows a probability of producing 64 defects per 1 million parts produced.
- A Cp of 2 is basically Zero defect territory.
