It took almost 20 years to drill that deep but the hole is only around one third of the way through the Earth's crust with temperatures already reaching 180 degrees Celsius (356 Fahrenheit).

It starts with knowing what workpiece material you have and what tooling and how you will be using to machine it.The combination of these two factors determines your initial Cutting Speed and Chip Load that you can put into the speed and feed formulas to calculate the cutting tool RPM and feed rate.

2023731 — A number of techniques, such as combustion, electric heating, solar thermal, and geothermal, can be used to produce industrial heat.

was set appropriately? Surely the maths would mean that if spindle speed is advised at say 6000rpm with 300mm/min feed but you had a 12k machine ...

The short answer is that "fine" threads are stronger than coarse threads. Without getting too technical we will explain the advantages of using fine threads.

Feedspeedformula

Cutting Speed is the speed at which the tip of the tool travels through the material. It is commonly expressed in Surface Feet per Minute (SFM) or Surface Meters per Minute (SMM).

Since cutting speeds can be in either Imperial (SFM) or Metric (SMM or m/min) units, you have to use two formulas to calculate the RPM.

It's reported there was no money to fund such projects after the collapse of the Soviet Union and three years later, in 1995, the whole facility was shut down.

For turning applications, we do not need this formula since Spindle Speed is usually given in Constant Surface Speed (CSS), which uses SFM value directly. But if you still want to use the RPM formula, then the diameter value is the actual diameter of the workpiece.

Calculate Speeds and Feeds for 1/2" (0.5 in) 2 flute end mill in Mild Steel at cutting speed = 100(ft/min), Chip Load=0.001(inch per tooth)

The formula is used for milling and drilling applications. Please note that some tool manufacturers provide their recommended feed rate as feed per revolution. In such cases do not multiply by the number of teeth.

Feedspeedcnc

One of the primary tasks machinists must learn to perform is a calculation of speeds and feeds required for milling, drilling, and turning.

Drilling was stopped on the Kola Superdeep Borehole in 1992 when the 180 degrees Celsius temperature was reached, said to be twice the temperature expected at that depth, with drilling any further impossible as tools could not cope with the heat.

When you have manufacturers' data simply find your tool in the catalog and cross-reference the cutting speed and chip load against the tool diameter:

"There used to be common understanding among Western scientists that the crust was so dense 5km down that water could not permeate through it.”
