7.3. Feeds And Speeds Calculator

With the Feeds And Speeds calculator, you can calculate estimated values for F (feeds) and S (speeds) in your program. Please understand that feeds and speeds depend on many factors and it is your responsibility to make sure that the values calculated by the calculator do not inflict damage on your machine or hurt people.
You can either type in the tool diameter and the number of teeth manually, or you can use the Get Tool button to fetch these values from your tool registry. Please note that for this to work, you need to have predefined your tools with the Number of teeth value set.
When you enter the feed data, you can either fill in Feed per tooth or the Cutting feed and for the Speed, you can either fill in the Cutting speed or the Spindle speed.
As soon as you change a value, the calculator recalculates the other values for you.
You can also click the Materials button, to fetch predefined values for Cutting Speed and Tool Feed.
This dialog has three tabs, one for your own predefined materials and two for example materials for milling and turning.
To define your own materials, press F2 to open the Inventory browser and click on the Materials tab. Fill in all information about your material, and make sure you fill in the Feeds and Speeds values.
This will make it easy for you to fetch these values via the Materials button at any time.
You can also set your own example materials, or edit the ones already there. These are located in an installation subfolder called Misc.
The files are a list with comma separated values (csv) that can be edited with Excel or with any text editor like Notepad or other.
Finally, when all data is filled in, you can press the Insert F & S at cursor button to automatically insert the calculated values in the program.
