The RBR Machine Tools CncGcoder machining calculator app was developed as a tool for chip cutting metalworking machinists to quickly calculate starting speed and feed conditions for many common machining operations. This unique tool is based on formulas developed during RBR Machine Tools 28 years of experience helping customers program CNC machine tools. Unlike other speed and feed calculators, the RBR Machine Tools CncGcoder machining calculator does not require users to drag out heavy machining reference handbooks to use it. The calculator's built-in material database conveniently allows quick calculations right on the shop floor.

To use the calculator simply enter your machining parameters:

Cutter Diameter
Material
Hardness
Cutting Edges
Machining Operation
Cutting Type

Then choose a tooling material (high speed steel, carbide, and coated carbide) at the top of the screen and your results will be displayed in inch or mm units.

Calculations are available for these common CNC machining operations:

Turning
Face Milling
End Milling
Drilling
Coolant Feed Drilling
Boring
Grooving
Cutoffs

The machining calculator's built-in material database supports cutting in these material types:

Alloy Steel
Aluminum
Aluminum Die Cast
Brass
Bronze
Carbon Steel
Cast Iron
Copper
Ductile Cast Iron
Free Cutting Steel
Inconel 718
Stainless Steel
Titanium Alpha-Beta
Zinc
