As production tolerances become ever tighter and the error margin for measurement results shrinks, manufacturers must consider thermal fluctuations in their inspection processes.
Determining the shape of a workpiece is required in many manufacturing processes. Keep in mind these important points to ensure that you master the process.
Differential gaging measures using two devices, which has advantages over standard, comparative measurements using a single sensing head. These include the ability to measure size without regard to position.
Surface measurement is becoming increasingly important to ensure proper performance of a manufactured product. Advanced surface measurement tools are not only beneficial in the manufacturing industry but also have unconventional applications.
Modern electronic height gages are computer-based, touchscreen-operated systems that enable automated measuring routines, error correction and multiple probe offsets, much like a CMM.
Understanding the differences between measurement methods means their discrepancies can be explained and used as an advantage to produce better correlation.
Measuring surface finish at the point of manufacture is often done by the same machinist who is manufacturing the part. They need tools that meet test requirements and are easy to use.
