Spiral Bevel Company - Currently leading 3,4,5-axis CNC milling is more accurate tooth generating process compare to the previously used 7-axis tooth generating process known as Gleason or Klingelnberg. The traditional machining process known as Gleason/Klingelneberg requires iterations in spiral bevel tooth cutting called contact pattern development. For example, a typical machine summary sheet from Gleason provides so-called “PROPORTIONAL CHANGES”. “PROPORTIONAL CHANGES” reduce the number of iterations in contact pattern development. Because of numerous iterations, the production time and product cost increases. At least one extra gear needs to be manufactured in order to do the “PROPORTIONAL CHANGES” recommend by Gleason. Gleason and Klingelnberg gear cutting process requires resetting the production machines and repeat tooth cutting until reasonable tooth geometry is achieved. Gear manufacturers try to reduce the number of iterations in order to cut cost. In result, the gears are delivered with less than ideal tooth contact. 3,4,5-axis CNC tooth milling produces a required tooth contact pattern without iterations if our Spiral Bevel software is used.

Software for 3,4,5-AXIS CNC MACHINING OF gears

1. Contact us with your gear data or pdf drawings. Sample drawing.

2. Purchase 3d gear tooth software. Sample IGES file.

3. Cut spiral bevel gears on 3,4-axis CNC milling machines. Example of 3-axis cutting.

We supply software and 3-dimensional IGES models ( sample 1, sample 2, sample 3, sample 4) of spiral bevel and other gears. Our customers use 3d models to program 3.4,5-axis CNC machines to cut spiral bevel gears (sample 1_1, sample 3_1)

With our high-resolution tooth contact simulation software we can inspect our IGES gear models before manufacturing. Controlling the tooth contact increases tooth contact area for 50% without reduction of sensitivity to misalignment. Root area of the tooth can be also optimized for reduction of the bending stress for 30% or more. If the tooth form is optimized for highest area of the contact and lowest level of the root stress the size of the gear can be reduced.

CMM tooth inspection method is more accurate compare to rolling inspection. Rolling testers have been commonly used for manufacturing of Gleason and Klingelnberg gears. More accurate CMM inspection method is used when gear tooth is cut on 3,4,5-axis CNC.

CNC gears tooth cutting process produces the finished and correct tooth surface at the first iteration. Previously used tooth contact development is not needed if the correct 3d CAD tooth model is used for CNC machining. Before delivering 3d IGES model we can accurately verify the tooth contact and transmission error.
