January 17, 2012 - A manufacturer of carbide cutting tools for metalworking is using high precision laser displacement sensors from Micro-Epsilon to measure the width and height of cutting discs.
Cutting discs for the metal working industry are amongst the most common wear parts. In modern production, turned parts are manufactured to sub-micrometer precision. In order to ensure the accuracy of the machine tool requested, precise positioning of the tool is necessary, including the cutting discs.
Carbide cutting tool specialist Ceratizit relies on a measurement system that uses the optoCONTROL 2500 sensor during production control of the cutting discs. The measurement set-up was designed and developed by Benzing Feinwerktechnik. The vertically mounted optoCONTROL 2500 sensor traverses along the measurement object supported by a pneumatic processing unit. According to the shadow principle, the measurement system detects the width of highly sensitive cutting edges in order to offer reliable measurement results with respect to the distance and height of the cutting edge lines.
The design of the measurement system is both simple and cost effective. Furthermore, the system can be used as a mobile unit. Since the wear-free system works without touching the cutting disc, it has a minimal measurement time. The measurement data detected is transferred to a PC for further evaluation. The target object is assessed very quickly as the latitude is displayed graphically.
Micro-Epsilon’s optoCONTROL 2500 is a non-contact, laser-based measurement sensor that uses an integral, high resolution CCD camera for dimensional measurements. The sensor offers a high sampling rate (2.3kHz), combined with excellent repeatability (< 3µm) and resolution (< 1µm).
OptoCONTROL measures the dimensions of a target or the position of an edge using the ‘shadow principle.’ The system consists of a sensor unit and a controller. A parallel light curtain is produced using a laser light source. The CCD camera in the receiver section measures the ‘target’ contour formed by the shadow. The sensor unit is controlled and evaluated by an intelligent controller, with a graphical display provided for operation and measurement functions.
The optoCONTROL series is used in production and quality assurance areas for non-contact, highly dynamic measurements on running conveyors, extrusion lines, drawing processes, on machines and in automated production plants.
Micro-Epsilon is a major global manufacturer of sensors, headquartered in Germany. The company’s range of displacement sensors measure everything from to distance, position, vibration, dimensions and thickness, using both contact and non-contact measurement techniques. These techniques include 1D, 2D and even 3D laser-optical sensors and systems, eddy-current, capacitive, LVDT & inductive, potentiometric and draw-wire principles. Additionally Micro Epsilon has developed its own range of non-contact infrared temperature sensors that can measure virtually any target temperature from -40 to +3,300°C.
