Transcript
Make it exactly this size. Lovely request. Real manufacturing needs an agreed definition of acceptable variation.
A dimensional tolerance describes the permitted variation for a specified dimension. The drawing and applicable requirements provide the actual limits.
A part can look right and still fall outside those limits. Suitable measurement helps establish whether it meets them.
A stricter limit is not automatically better for every feature. Requirements should follow the job, not someone's enthusiasm for extra decimal places.
Bronto prefers precision to guesswork. Start by understanding what the part must do, then explore manufacturing at Machine Blue Book.
