The last meeting of the ISO Workgroup 13 on bevel gear calculation took place on the 23rd and 24th of May 2013 at the KISSsoft AG, in Switzerland. The topics were mainly the strength calculation of bevel and hypoid gears according to ISO 10300. In addition, a new Technical Report for sample calculations is in the works, to illustrate the calculation process. The KISSsoft team thanks the ISO Workgroup for the visit and looks forward to a further active and successful cooperation within the Workgroup!
