(12 cards)
What is quality control
Quality control is a range of checks, tests and processes employed by manufacturers to ensure their produce meets a standard that is acceptable to them before its good to leave the factory
Explain how quality control is carried out
-begins with the inspection of raw materials required for the manufacturing process and ends with packaging and delivery of product to consumer
-involves the inspection at all stages of manufacture- focuses on physical processes and actual product
-requires the company to create an environment which both management and employees strive for perfection
What is quality assurance
-any systematic process of determining whether a product or service meets specified requirements
-establishes and maintains set requirements to developing/ manufacturing reliable products
What are the advantages of quality assurance
-costs are reduced due to less wastage and reworking of faulty products as the product is checked at every stage
-improve worker motivation- have more ownership and recognition for their work
-prevents defects before they occur
What is a jig
A device that holds and guides a tool to ensure the process is accurate and allows for repeatable operations- drilling, tapping or welding
What are the advantages of JIGS
-increased accuracy
-faster production times
-lower manufacturing costs
What is a fixture
Designated to hold a workpiece in a specific position, or orientation, allowing a tool to perform a task on it with precision and repeatability
What is ameasuring device
Used to quantify various aspects of a product, helping QA engineers identify deviations from standard and maintain consistent quality, eg calipers, gages
What is an example of a measuring device
Spring- when springs are manufactured, measuring devices are used to test a sample from a batch- the key measurements are within an acceptable tolerance
What is an example of a template
Electric guitar- an accurate profile of the guitar is generated using templates using a CNC machine. These templates are placed on the selected wood, drawn around and cut out using table saw and routers.
-Templates aid accuracy and ensure consistency during manufacture- assisting quality control
How is ICT employed in QC
Ensure components are the correct type, size and correctly positioned
-used when testing the product- ensure it’s the correct standard before distribution
How is ICT employed in QA
-ensure staff training, administrative procedure and quality monitoring of a product at various stages of manufacture- ensure its the highest standard
-used to gain customer feedback- ensure consumer satisfaction
