Question 23

Why accuracy is important

Answer 23

Small deviation can result in product being not fit for purpose and would need to be remade > extra cost>extra time>deadlines not met

Question 24

Jigs

Answer 24

Custom made tools
Designed to achieve accuracy, repeatability and interchangeability during product manufacture
Ensure parts of product are made exactly the same, without the need for marking out
e.g holes drilled in exactly and place on different pieces of wood, printed circuit board jigs used to test for faults in electronic circuit

Question 25

Templates

Answer 25

Used to draw shape onto material which can be cut around
Useful when large number of complex identical shapes have to be cut

Increased use in CNC equipment reduced need for jigs and templates but still importany

Question 26

Patterns

Answer 26

Type of template
Used in textile industry
Trace parts of a garment onto fabric before it’s cut
Usually made from paper but can be made from studied material e.g catdboard if going to be used repeatedly
Clothing manufacturers usually employ specialist pattern makers as it is a highly skilled job
