X8- Changing SFM on a tool

[Randy Wolff]

I have started experimenting with X8. The material files we use have been changed so the number put into the old % of material cut speed is the actual sfm for the tool. When you open a tool in X8 there is no such box listed to teak the rpm of the tool. You can over write the rpm but if the speeds are reinitialized

it will go back to the original setting. The only way I have found to modify the rpm and make it stick is to due the following:

Open the operation, go to the tool tab, right click the tool. Click on the feed and speed calculator, change the % o material cut speed. Click update which

brings up the Tool Manager. Click recalculate, click finish, green check on the speed and feed calculator. This will update the speed and feed rate only. If

the plunge rate or retract rate change you must also right click the tool again and click re-initialize feeds and speeds to update them also.

Am I missing something or is this now what has to be done? I see if you open up the tool data base in the separate Tool Manager program the sfm can be changed in the properties there but that will change the data base and not just the tools for the current job that is being programmed.

Thanks,

Have you changed the default process from lock feedrates to not use that process. For many years people complained the feedrates would not stay locked. CNC Software put that process as the default now. If someone is going from an older version to X8 they will see what they see as a big difference. For those going along and along with version it will be something they adjusted to some time ago. Different jobs I use the lock feedrate and in other jobs I turn it off. Really comes down to how or what you want to do.

No, I do not have feed rates locked. This is just opening up a tool in an operation and wanting to change the sfm of a tool. When you hit the recalculate button the sfm is referenced from the material but seems to be unavailable to now change when you have a tool open.

Randy, I also program the sfm like you, or should I say used to. I have yet to figure a good work around to this issue and am looking forward to learning how to work with the new way.
