Statistical quality control (SQC) began in the 1930s with paper, pencils and slide rules. By the 1970s, SQC was performed with electronic gages, data loggers, and PCs. Today, it is done with even more powerful and complex machines. The machinists who operate these machines often have to act as CNC programmers. In addition, they must be able to perform inspections to verify their processes, which requires extra skills. Data collection techniques have become more complex, but they should remain simple for the user. SQC programs typically are capable of collecting and recording data, but only now are unique gage identifiers being captured with measurement data.
Key Takeaways:
- SQC is a time-consuming and cumbersome process that has been used since the 1930s.
- The machinists of today are highly-trained and skilled workers focused on the production of parts.
- In order to meet data collection demands, some gages now have the ability to transmit an identifier that includes measurement data.
“Thus, one of the first steps in implementing machinist-conducted transparent data collection is making the tools as simple as possible for the user.”
