im looking for software that will enable me to cut many types of gears ,
Anything that i have found ether only cuts spur gears or there is no support in SA .
Any help would be appreciated ..

I'm picking that you are after gear generator software and will use your Cam software to generate the code for your machine.
If so have a look at this software.
Gear template generator program
There is a free evaluation version so you can see if it does what you want.
Hope it helps
Cheers

Hi Peter

I will have a look and will post if it helps me or not ,
The program i use at the moment to generate codes for our machines is EdgeCam, hopefully Gear template generator will work !
Thank you very much

This is good as it will compensate for tool thickness under module. http://www.delphusa.com/

it looks good ,
thank you
however is there a way to do helical gears, bevels and spiral bevels ?
or do you know a program that will ?

[RICHARD ZASTROW]

What type of machine are you using to make gears? A CNC gear hobbing machine? Or?????

previously we have been using a range of manual machines , however would like to start using milling machines .

[RICHARD ZASTROW]

A milling machine may be capable of making some gears in low quantities. They are not productive enough to be used commercially. A 3-axis milling machine with an indexing head can produce spur gears.

If equipped with either a low-lead attachment (manual machine) or a 4th axis contouring dividing head can produce helical gears if the machine can be adjusted to have the form gear milling tool set to the lead angle of the helix. If using an endmill with the tooth form ground into it, the lead angle adjustment wouldn't be required. Both of these methods are very unproductive except for very low volume production.

Additionally, you must be able to measure what you produce. You will have to measure lead error in order to make lead corrections. How are you going to measure tooth form? Tooth spacing error? Typically, this requires a gear analyzing/inspection machine to be credible with client/customers in todays quality conscious world.

Many wonderfull things can be produced on multi-axis mills/machining centers including gears. Question is; Is this an economical or efficient way to make gears?

Dick Z , thank you for your reply .
we have 4 axis and 5 axis machines and a few grinders that would be able to rectify any lead errors ,
The company is a jobbing shop so most of the gears that come in are one off ,
however we have all the equipment needed for analyzing and inspecting ,

the reason i am researching about trying to make what we have work is because our manual machines just take way too long .
and the old technology leaves too much for human error..

I have just purchased bob cad . do you thing this was a wise option or was it a waste of money ?

The gear industry has developed interactive software. This software asks for input from the gear machine operator such as a description of the gear and the cutting/grinding tool. The gear description can be input to the control directly from the gear's print data. Once input, the program can be stored and recalled in the future for a repeate order.

My associates and I design/build gear hobbers etc. including the proprietary software. The software was developed over 20 years of experience. Other gear cutting/grinding/inspection equipment manufacturers have developed their own software as well.

A control manufacturer, NUM, has also developed gear manufacturing software.

None of these alternatives is inexpensive. There are machine retrofitters (manual to CNC) in Europe and the USA.

I have no idea as to the value of Bob CAD. I use only AutoCad for design/prints. As I said, our controls (and the others) are interactive with the machine operator so no CAM system is needed to produce a CNC control program.

Hope that helps.
