Wspomaganie kszta?towania ostrzy narz?dzi skrawaj?cych systemem wizyjnym

摘要

Cutting tool inserts have well-defined geometry [1, 3, 4, 5, 6]. Companies producing tools try to develop tool geometry adapted to different types of cutting conditions [2]. Specifically, a cutting wedge is changed by creating a tiny chamfer on the flank within the rounded cutting wedge from the minor flank side. It is a small shortening of the wedge and allows avoiding the wearing-out of the cutting edge in the initial phase of its work while favourable distribution of irregularities on the edge is created [3, 4, 5, 6]. Modification of cutting tool geometry is performed on a stand constructed specially for this project. Due to the small depth of cut, in tens of micrometers, the control of grinding tool displacement was realised with use of a vision system. A camera was located perpendicularly to the cutting zone. It enables the grinding tool displacement to be observed on the screen. The measurement capacity test performed took into account the linear stage measurement uncertainty and the uncertainty of scene object edge identification by an operator. The carried out tool wedge modification both for milling and turning operations proved the usability of the proposed methodology of visual control in practice.%Artyku? przedstawia sposób modyfikacji ostrza skrawaj?cego w postaci niewielkiej fazy na naro?u ostrza od strony pomocniczej powierzchni przy?o?enia. Ze wzgl?du na ma?e rozmiary przeprowadzonej modyfikacji autorzy zaproponowali metodyk? kontroli wielko?ci modyfikacji z podgl?dem strefy skrawania. W artykule przedstawiono uk?ad wizyjny podgl?du strefy skrawania oraz oceniono zdolno?? pomiarow? tego uk?adu w aspekcie przeprowadzonego skrawania. Badania potwierdzi?y przydatno?? proponowanej metodyki.
