All data are in SFM - surface feet per minute. 
If you have metric data divide it by 3.28
1 m = 3.28 ft

	==== EXAMPLE ====
	Bronze  
	C22600, C65100, C65500, C67500 
	55
	1.5
	=================

4 lines for each material 
line 1: Name
line 2: description
line 3: Speed in SFM
line 4: power constant - to calculate needed HorsePower 
and then again 1, 2, 3, 4
