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 3-dimensional IGES models ( sample 1, sample 2, sample 3, sample 4) of spiral bevel and other gears. Our customers use IGES models to program 3.4,5-axis CNC machines to cut spiral bevel gears with better accuracy and at reduced cost compare to previously used Gleason and Klingelnberg (sample 1_1, sample 3_1) generating.

SPIRAL BEVEL GEAR Software

 

 Our gear software available as add-on to CAD products as SolidWorks, Pro/E, UG, CATIA or other, and as IGES export option from MS Excel.

      Because of the complicity of the tooth geometry, better spiral bevel software has been always very critical for manufacturing.
       Spiral Bevel Co has adopted Direct Digital Simulation (DDS) method, as an underlying mathematical algorithm for writing of software. DDS method has shown advantages compare to the traditional differential geometry method that is used in software form, for example, Gleason or from Klingelnberg. The key advantages of the DDS modeling method versus traditional method are: reduced cost of calculation, ability to calculate complex tooth geometry, higher accuracy of tooth geometry calculation, higher accuracy of tooth contact simulation, and higher resolution of visualization.

      We are offering customer support in manufacturing of spiral bevel gears on 3,4,5-axis CNC machines. While our software is available for purchase, we recommend to use our gear experts to do all the critical tooth calculations. 

       Design software.

 

        Because Spiral Bevel software provides accurate geometry of the tooth root we can accurately use Finite Element Method (FEM, FEA) for calculation of the root stress. Calculation of the root stress is criticald for prediction of the fatigue of the gear tooth on bending.
       Spiral Bevel software allows optimizing all the parameters of the spiral bevel gears.
We do not simplify gear design for easy manufacturing. The cost of our Spiral Bevel manufacturing process does not increase for a better tooth geometry.

       Manufacturing software.

       The first version of our manufacturing software has been developed and used in production of spiral bevel gears in 1986. We have an extended experience in traditional spiral bevel gear manufacturing for automotive, aerospace, marine and for other applications. In 1986 we developed the software for simulation of common Gleason and Klingelnberg gear manufacturing methods. Originally our software would calculate the tooth geometry from the machine summary in order to predict the finished geometry of the gear tooth. The reason for the original development of our software was a to develop a mathematical model of the tooth that allows more accurate gear manufacturing compare to the mathematical tools used by Gleason or by Klingelnberg. Our software has been used in traditional gear manufacturing since 1986 and demonstrated advantages.

       Tooth Contact Analysis (TCA).


         TCA is critical in manufacturing of gears. Do not purchase gears from a company that can’t predict tooth contact before manufacturing of gears.

TCA software from Spiral Bevel Co calculates the tooth contact area, the immediate and combined contact pattern, the contact pass, sliding velocities, rolling velocities, and all the mentioned data in animation while gears rotate in mesh. Calculation of the loaded contact pattern is conducted with help of FEA software. The software accounts for the bending deformation of the tooth and for the compression of the tooth surface.

          Our software is capable to reproduce the exact 3-dimensional tooth geometry existing gears. If the summary is not available, the software can reproduce the original Gleason or Klingelnberg summary from the CMM inspection data.
In practice, our software helps us to reverse engineers and manufacture gears and pinions so we can supply replacement parts.
