I appreciate that many people have devoted time to preserving and sharing their accumulated knowledge of machining materials.
What I am looking for is a way to specify the material type to be machined, part or slab thickness height from waste board, and some information on the machine (as mentioned: rigidity, as well as torque for spindle and steppers/servos, spindle RPM range, and maybe cutting area). After that a recommendation for end mill, speeds and feeds, etc. would be the result in a human readable format. I’m not recommending this because I’m lazy, I think an app like this would help bring many more people into machining that are otherwise intimidated or struggle with other aspects of machining, but are very capable creative people who just want to make stuff.
