PublicationFeindrehen von Gußeisen mit hohen Schnittgeschwindigkeiten( 1995)
;Spur, G. ;Becker, K.Lachmund, U.In the past years, rising requirements on productivity and quality have lad to high cutting speed. Especially superhard non-metallic cutting materials brought progress in this field. This study deals with high speed finishing of lamellar gray cast iron with ceramic cutting materials and cubic boron nitride. The results show that the application of high cutting speeds loads to a considerable reduction of processing times. Regarding the tool life the application of cubic boron nitrid, especially with cutting speedover Vc =1000m/min, yielded the best results. High surface qualities can be reached up to a cutting speed level of Vc=2000m/min. -
PublicationThe machinability of fibre composites( 1993)
;Lachmund, U.Krismann, U.This paper presents the results of technological investigations into the machinability of fibre composites. In many cases, machining is required during the manufacturing process for fibre composite parts for reasons associated with the material and the type of processing. The possibilities and limits on the machining of fibre composites are illustrated with the example of turning for chip-forming machining and with the example of laser beam and water jet cutting for abrasion. The results of technological investigations are presented, showing the attainable machining quality as well as characteristic types of material damage. A comparison of the abrading processes gives an indication of their suitability for the machining of fibre composites.
