computer aided manufacture Flashcards
what does CIM stand for?
computer integrated manufacture
what is a CIM?
a complete system where computers manufacture a product
what does CIM start off with?
- computer aided design (design is created by a computer)
2.computer aided manufacture (product is made using a computer) - automated storage and distribution
CIM controls everything.
what is computer aided design?
a product is designed on a computer.
when the design is finished, the functions are stimulated on a screen before a prototype is made
what is computer aided manufacture?
computers control CNC machines like laser cutters to make a product
how does a computer do quality checks?
the computer tests the product using computer inspections
what is CAT computer aided testing used for?
analysing strength and efficiency of a design
what are the benefits of CAD and CAT
no physical models are made which saves money, time and waste
what are the advantages of CAD?
-designs can be created and edited easily which saves time
-parts of the design can be easily copied or repeated
-it is very accurate
what are the disadvantages of CAD?
-software is complex to learn
-software can be very expensive
-security issues- like chance of being hacked
what are the advantages of CAM?
-faster than traditional tools and machines
-more accurate
-high repetitive accuracy
-machines can run 24/7
-can produce directly from CAD files
what are the disadvantages of CAM?
-expensive set up costs for equipment
-training costs and time
-CAM machines need specialist engineers for maintaining and repairing the machines
-has led to unemployment as the machines replace people
what does CAD help with in designing?
Cad can help visualise the product when it’s made. it can:
-check sizes and proportions
-test out different colour schemes and materials
-place the product in a context or scheme
what does CNC stand for?
computer numerically controlled
what is CNC?
machine tools that are controlled by a computer
