Question from daniel:

hello i work at an engineering workshop the other night i was asked to machine an arc shaped groove into a peice of metal the cord length was 6 mm and the height from the middle of the cord to the arc was 1mm i was hoping to find the diameter of the cutter needed to do the job and also the formula to work out how to find the diameter. i believe it is 10mm dia thankyou for your time and knowledge

Hi Daniel.

Penny had a similar question to yours a few days ago. In her answer, she shows how to calculate the radius, which is half the diameter. That method will work for your figures as well.
