These jigs are usually composed of multiple parts and have precision processing and adjustability to ensure accurate measurement of all aspects of sheet metal parts, enabling them to accurately and quickly measure and verify the size and shape of various precision sheet metal parts to ensure that they meet design requirements and quality standards.

[0003] The existing sheet metal measuring jig uses a caliper to measure the length and width of the sheet metal when in use.
