Do contractors overcharge?

Although a 10-20% project cost overrun is normal with even 'good' contractors, a 50-100% cost overrun is not normal and could be indicative of a dishonest or bad contractor. Some cost overruns are normal because contractors must make some assumptions upfront about things they cannot see.

What can a 3 axis CNC machine do?

3-axis machines are typically used for machining of 2D and 2.5D geometry. Machining of all 6 sides of a part is possible in 3 axis machining but a new fixturing set-up is required for each side, which could be expensive (more on that below). For a single fixture setup, only one side of the part can be machined.
