WARNING: Machine tools present a safety hazard. Improper operation can result in severe injury.

Never use a machine tool without the supervision of a qualified instructor.
Rigidity is one of the most important aspects of good machining practice. The milling machine itself must be set up in a very rigid manner as shown in the animation below. But it doesn't just stop there. The rigidity of the work piece setup (how strongly it is attached to the machine) is very important too. With a rigid work holding setup vibrations are less likely to be transmitted from the cutting tool to the work piece resulting in a better surface finish , longer lasting tools, and higher precision.
Rigidity is mentioned often in these topics and for a very good reason. Rigidity is one of three key elements to good machining: The three key elements are: rigidity, coolant, and cutter. A rigid setup is a must to reduce vibrations. A good selection of coolant is also important because it keeps heat low, chips cleared, and the cutter sharp which is the third element. If the machinist constantly keeps these three things in mind he/she will produce quality work in less time. R.S.
