    摘要: A coordinate measuring apparatus includes guides made of aluminum. Scales which are also made of aluminum are used to measure the position of the measuring slide movable on the guides. In a preferred embodiment, the scales are in the form of a reflection phase grating and are applied directly to the surface of the guide member. In addition, a temperature sensor is provided which measures the temperature of the guide member and of the scale divisions. A method of producing the scale divisions is also disclosed.
