Compensation without cables
Thermal compensation of a coordinate measuring machine's principle structural components and the part being measured helps ensure measuring accuracy over an extended temperature range when the CMM is installed outside of a temperature-controlled area. Such a temperature-compensation system is comprised of temperature sensors and cabling running through the machine to its controller. The more sensors there are the more accurate the system, but these cables can cause mechanical issues and will eventually fray or break because of the constant CMM motion.
