Investigation of Optical Distance Sensors for Applications in Tool Industry : Optical Distance Sensors

Abstract

The objective of the study was to increase the productivity of a Computer Numerical Controlled Machine used for measurement process followed by machining process. The machining process of the CNC machine was inevitably fixed due to machining parameters. However, it was possible to decrease the time of measuring process by replacing its mechanically operated, contact probe, displacement measurement system with an optically operated non-contact laser triangulation or confocal chromatic displacement measurement system. The work was commissioned by the GFE and both measurement systems were bought. The additional required parts were made in the workshop. Several experiments were conducted in order to define the most suitable and compatible measurement system with the most efficient timing for the required CNC Machine. The selected measurement system was further tested and upgraded to achieve paramount results. As a result of this thesis, an optically operated, non-contact laser triangulation, displacement measurement system proved to be the most suitable, affordable, and compatible to decrease in process measurement time in order to increase productivity.
