Abstract
An on-machine measuring system based on the use of an LTP optical head was developed to accurately measure the slope error and profile error of long parts just after machining. Cylindrical surfaces can be measured completely by steering the beam up the sides of the cylinder with a rotatable mirror. To increase the reliability to measure the cylindrical surfaces, the optical system of the LTP head was improved. A personal computer collects all the data and controls the machine positioning and the beam steering mirror automatically.
