Quality Assurance
Quality Assurance is the responsibility of the Quality department; the goal is to guarantee consistent results throughout the organization and is accomplished by implementing systems that ensure that processes are in place to verify form, fit, functionality and design intent. These processes include document control and inspection techniques, such as first article, in-process and final inspection. Quality assurance is independent of particular components or assemblies; it is the roadmap by which the manufacturing department must navigate the production process
Quality Control
Quality Control is the responsibility of the Process Planner; the person who decides how the component will be manufactured, the sequence of operations, how the parts will be set up and what tools will be used. This person documents the process, provides instructions to shop floor personnel, solicits feedback from the production workers, updates the source programs and maintains an organized file system. The Process Planner or CNC Programmer must work closely with quality personnel to define the quality plan for each product the company manufactures. Each component or assembly has its own complications and the quality plan will determine the success or failure of the build. It is extremely important to devise a custom strategy for each job that ensures compliance, but does not slow down production by adding redundant inspection procedures. 100% inspection of job lots, is neither necessary, nor desirable.
We will begin a series of courses over the next few weeks to show you how programmers can cut a companies' defect rate to practically zero. It is important to understand, that to be a good CNC Programmer; you must be a very good Process Planner.
