Features: 

*** Turning (Lathe) *** 
- Calculate RPM given Cutting Speed and Cutting Diameter
- Calculate Cutting Speed given RPM and  Cutting Diameter
- Calculate Machining Time given Cutting Length, RPM and Feed/Turn 
- Metric and Imperial units (mm, inch)

*** Milling *** 
- Calculate RPM given the Cutting Speed and Tool Diameter 
- Calculate Tool Feed Rate given Feed/Tooth, Tool Diameter and number of tool teeth
- Calculate Machining Time given the Feed and Cutting Length
- Metric and Imperial units (mm, inch)
  
*** Drilling *** 
- Find RPM given the Cutting Speed and Tool Diameter
- Find Feed Rate given the Cutting Feed (inch/rev) and RPM
- Find Machining Time given the cut length and feed rate
- Metric and Imperial units (mm, inch)
