High feed turn milling

Abstract [en]

Due to the fact that turn-mill machines are getting more common in engineering industry it will be more interesting to develop tools and application methods, which is utilising the low dynamic stability in this kind of machine tools. One way to increase the productivity in turn mill machines is to adapt the milling tool after the low stability in the milling spindle and the turning spindle. The removal rate and the productivity can largely be increased with "High Feed Turn-Milling" and the newly developed tool CoroMill 210. This machine tool is designed for complete machining and a consequence of this is that the milling spindle bearings are rather weak. Regenerative chatter is the vibrational mechanism which in most roughing applications limits the possible removal rate. Traditional tools have a rather long lever from the cutting position to the rotation centre of the bearings. The dynamic stability in the machine should be in the direction of the chip thickness. The milling spindle and the c-axis will act stiffer when using tools with a low approach angle like the CoroMill 210 compared with tools with 90 or 45 degree approach angle. To reduce the risk for forced vibrations it’s necessary to consider the engagement of the cutter. The software available on the market has little control of the feed speed when linear and rotation motions are performed simultaneously.
