Titanium Machining: The Effect of the Cutting Parameters

Titanium having a density only about 60% of steel has a far greater strength than many steel alloys. However, titanium has many difficulties in machining. It has a low conductivity and therefore heat due to cutting does not dissipate quickly. This results in concentration of heat on the cutting edge and hence greatly limits the machinability of this material. 


In titanium machining tool life is greatly affected by the following cutting parameters listed in the order of decreasing effect, i.e., the least influential one for tool life is the one at the bottom of the list:

• surface cutting speed
• radial depth of cut
• feed per tooth (chip thickness)
• axial depth of cut

Chatter: Root Cause and Tap Testing

Chatter vibration is one of the biggest headache of production engineers, machinists, and NC programmers. Chatter degrades part quality, reduces productivity and shortens tool life. Without getting to the bottom of the problem, production engineers can only rely on trial and error to eliminate this problem. But what is it that causes chatter?
