Basic Instructions
Successful Milling is all about Speeds and Feeds
Speeds refers to your spindle speed in rpm.
In a series of experiments performed early on in machining, it was determined that spindle speed is the biggest determiner of tool's life.
Running too fast generates excess heat (there are others ways to generate heat too), which softens the tool and ultimately allows the edge to dull.
Feeds refers to the feedrate, in linear mm per minute.
Feedrate is all about the tradeoff between maximizing the material removal rate. Material removal rate is how fast in cubic units the mill is making chips--the faster the better for most machinists, right up until it creates problems.
The most common problem is tool breakage or chipping when you feed too quickly.

Advanced Operational Knowledge
There are some more advanced tasks that not everyone needs to know to print, but needs to know to troubleshoot:
Warnings
- Keep loose hair and sleeves away from all moving parts.
- Dust control
- Avoid inhaling dusts generated from milling operations
Safety
- Keep loose hair and sleeves away from all moving parts.
- Do not touch
- Dust
- Material Safety Data Sheets
- Root2CNC is not intended for:
- (A) Beginners
- (B) Cutting, milling, engraving metals
- (C)
