@LarryM, probably the easiest way to adjust feed rate is to “edit” the tool that has been “selected” from the database.
In the images above posted by @AllenMassey you’ll see next to the tool that has been chosen, there are two buttons, “Select” and “Edit”. Both will allow you to adjust feeds, depth per pass and so on, but there are important differences in why each is option is used.
Choosing “Select” allows you to select a tool from the database which will already have a bunch of ‘standard’ feed rates etc. changing any of these values here, will save those values in the master tool database.
If however you first “Select” a tool, and then use “Edit”, you can adjust all the tool parameters such as tool size, depth of cut, step over and so on, and these new settings will only be save in the current project (the master tool database remains unchanged).
As an example, when creating a job, I’ll regularly “Select” the 6mm end mill as my tool, but then use “Edit” to change the tool size to 6.29mm (the actual size of the cutting bit), I’ll then tweak the feed rate and step-over to suit the material I’m cutting. This means my database settings will remain unchanged (as will all the tool’s initial feed rate and step-over values), but each time I open this particular job, all my ‘tweaked’ settings are already set.
When making a new job that is very similar in cutting characteristics to something I’ve previously done, I’ll open the original file, select “Save As”, to save it as a new file, I then adjust the material dimensions to suit the new job and I’ll then delete all the unwanted drawing elements. I’m then left with a blank job that has all the feed rates, step overs etc that I already know to be appropriate for that type of material and I’m all set to begin anew…
Alternately, if I were to go and buy 50 new 6mm end mills, and I found that all of them were actually 6.29mm at the cutting tip, I’d go into the tool database and either change the dimension settings for the existing 6mm bit, or better still, I’d create a new tool, call it “6.29mm” and then copy all the data from the existing 6mm bit.
Hope this all makes sense. Let me know if you’ve any questions.
