Feed & speeds database

Hello World

We're looking into the Speeds & Feeds database with a view to using it to capture our proven cutting data and I was wondering if anyone has any experiences both good and bad of using it.

 

At our first attempt of testing it, it appears that Turning isn't supported at all even though machine data for this application can be populated within it, the lookup mechanism only works for DRILL and Mill.

 

Thanks in advance for you time in responding

Re: Feed & speeds database

Turning is supported, but it uses the legacy machining data library and not the new feeds and speeds interface, which you can configure through a dialog inside of NX.

 

For turning you must use a regular text editor and change the files directly.

 

Generally it works good, but there are some things to consider.

  1. We have disabled finding parameters based on diameter to length ratio, because they were always wrong. It is better to get notified about no parameter found than silently applied a totally wrong parameter.
  2. We use four entries for each diameter to get better results, tool length: 0.1mm, minimum, maximum and 1m.
  3. Tools like taps and chamfer mills get fixed values despite of the material.

"Set Machining Data" is the newer database for milling.

 

Speeds Library is the legacy function for turning and point to point. In the help, search for "The Speeds Library" 

 

Both use the same tables for part material, tool material, and cut type.
