If we take another look at the Mach 1 vs. altitude tables already discussed, we see that the speed of sound at 30,000 ft is 678.2 miles per hour. All we have to do is multiply this value by 3 to determine the speed of a vehicle traveling Mach 3 at 30,000 ft in miles per hour. The answer is 2,035 mph.ach number: Mach number is a quantity that defines how quickly a vehicle travels with respect to the speed of sound. The Mach number (M) is simply the ratio of the vehicle's velocity (V) divided by the speed of sound at that altitude (a).
Mach3 and speed. I need to know how to tell Mach3 to use a different (faster) speed when moving across and above stock surface on my DYI mill. Everything works fine, except that my mill has to run very slow to make up for a weak Z axis.ll 3 axes have to move 10, so the slowest axis, in you case the z, will slow the other 2 down. Now imagine going from x10 y10 z5 to x0 y0 z0. in this case the x and y have to move 10 but z only has to move 5, so if the max z speed is at least 1/2 or faster than the x and y it will not be the limiting factor.
