Manufacturing of straight bevel gears was in the past onlypossible on specially dedicated machines. One type of straightbevel gears are those cut with a circular cutter with acircumferential blade arrangement. The machines and the gears theymanufacture have the Gleason trade name Coniflex®. The cutters arearranged in the machine under an angle in an interlockingarrangement which allows a completing cutting process. The twointerlocking cutters have to be adjusted independently duringsetup, which is complicated and time consuming. The outdatedmechanical machines have never been replaced by full CNC machines,but there is still a considerable demand in a high variety of lowquantities of straight bevel ears. Just recently it was discoveredthat it is possible to connect one of the interlocking straightbevel gear cutter disks to a free form bevel gear generator and cutstraight bevel gears of identical geometry compared to thededicated mechanical straight bevel gear generator. A conversionbased on a vector approach delivers basic settings as they are usedin modern free form machines. The advantages are quick setup, highaccuracy, easy corrections and high repeatability.
