How does Spindle Torque come into play in machining?

Hi Bob,

I know that power and torque are mathematically related.  You talk about the power of spindles in your articles and videos, but not about torque (at least not in any I have seen so far).  How does torque come into play in machining?

Here is my spindle’s power/torque curves.   Since spindle rpm is just one of many variables to work with when deciding speeds/feeds…   Would it be better to lean toward 12K rpm if possible,  where the torque is greatest and then choose appropriate cutter, speeds, feeds, etc?

 

Power/Torque Curves

The two are fairly interchangeable for machining purposes so long as you have a power curve like you do.  The issue is typically to find the highest MRR (Material Removal Rate) for a particular operation that doesn’t require more horsepower than your spindle can deliver.

The G-Wizard Feeds and Speeds Calculator will automatically back off the RPM and then the Feedrate to stay within spindle power limits while respecting any power curves that are available.  Absent a power curve, it must assume full power is available at any valid rpm the spindle supports.

That doesn’t speak to the issue of any sort of optimization, though.  The result will be optimal if the spindle power peak is higher than the initial feeds and speeds that are chosen.  But if the power curve is less, it may be possible to get a better overall MRR by backing off RPM to get closer to the power curve peak.
