The auto-industry has high standards for engine parts. All main parts have to be accurately measured to ensure their geometrical characteristics [1]. For certain parts the acceptable variation of geometrical features and dimensions from nominal values is less than a few micrometers. A part that does not meet the measurement requirements can result in premature wear, transmission problem or even catastrophic engine failure. Coordinate Measuring Machines (CMMs) are widely used to measure geometrical features of engine parts. Commercially available CMM machines measure dimensions by collecting data using a sensing device or probe. CMM machines have been used to measure transmission parts of combustion engine cars. As the technology advances from combustion engine to Electric Vehicles (EV) the engine parts measurement become more challenging. The engine noise in EV is very low to the degree that is difficult to hear if an electric vehicles is ON or OFF. To maintain such a low level of noise, the variations of geometrical dimensions for engine parts from their nominal values have to be less than a few micrometers. Such a measurement accuracy cannot be easily achieved by current CMM machines. The main objective of this work is to design a non-contact CMM machine for electric vehicle parts with auto learning capacity to meet the measurement accuracy and resolution requirements for new generation of electric cars. If the proposed system is employed in the production line the benefit to the Canadian industry will be significant as it reduces the time required to test electric vehicle parts considerably. The potential sales of the family of products within this platform technology is expected to exceed $10M over its life. ****

汽车行业对发动机零部件有很高的标准。所有主要零件都必须进行精确测量，以确保其几何特性[1]。对于某些零件，几何特征和尺寸与标称值的可接受变化小于几微米。不满足测量要求的零件可能会导致过早磨损、传动问题甚至灾难性的发动机故障。坐标测量机 (CMM) 广泛用于测量发动机零件的几何特征。市售的坐标测量机通过使用传感设备或探头收集数据来测量尺寸。三坐标测量机已用于测量内燃机汽车的传动部件。随着技术从内燃机发展到电动汽车 (EV)，发动机零件的测量变得更具挑战性。电动汽车的发动机噪音非常低，无论电动汽车打开或关闭都很难听到。为了保持如此低的噪音水平，发动机零件的几何尺寸与其标称值的变化必须小于几微米。当前的三坐标测量机无法轻易达到这样的测量精度。本工作的主要目标是设计一种具有自动学习能力的电动汽车零部件非接触式三坐标测量机，以满足新一代电动汽车的测量精度和分辨率要求。如果拟议的系统在生产线中采用，那么对加拿大工业的好处将是巨大的，因为它大大减少了测试电动汽车零部件所需的时间。 该平台技术的产品系列在其生命周期内的潜在销售额预计将超过 1000 万美元。 ****
