Q1. What is the least count of cmm
Ans. 
The least count of a CMM (Coordinate Measuring Machine) is the smallest increment that can be measured by the machine.
• The least count of a CMM is typically determined by the resolution of its measuring system.

• For example, if a CMM has a resolution of 0.001 mm, then its least count would be 0.001 mm.

• The least count is important for ensuring accurate and precise measurements in quality control processes.
