Define dimensional accuracy in your own words.
Think about how important it is for parts to fit together.
What is one effect of tool wear?

What is dimensional accuracy?
Think about what it means for parts to fit together.
True or False: Tool wear can improve dimensional accuracy.
Consider how a dull tool performs.
A manufacturer must produce a cylindrical part with a diameter of 50mm ±0.05mm. If the tool wears down by 0.03mm, discuss the steps the manufacturer must take to maintain the required dimensional accuracy.
Think about regular maintenance and monitoring strategies.
Design a simple experiment to test how different amounts of fixturing affect the dimensional accuracy of machined parts. What measurements would you take?
Focus on how the degrees of security can impact the machining outcome.
