This project is about the design of jig for Coordinate Measuring Machine (CMM) in metrology
laboratory. The CMM is one of precision measuring devices for measuring the physical
geometrical characteristics of the product. Measurements are defined by a measuring probe
touch the surface of the product. Currently, the box and plasticine are needed as a vice
because there is no special vise in CMM to hold, clamp and support the workpiece. The
existing vice is not properly in the measurement process but its used for the workpiece with a …

Coordinate measuring machine (CMM) is one of the most popular devices in engineering
measurement. A CMM is a device to measure the geometry of physical specimen by sensing
on the surface of the specimen with the measuring probe. Unfortunately, the measuring
probe in Metrology Laboratory at UiTM Cawangan Pulau Pinang is not able to touch the
surface of the workpiece with a thickness less than 40 mm. In order to solve the issue, a jig
need to be used to hold and clamp the specimen and to ensure the measuring probe can …
