Trochoidal milling high metal removal A strategy that delivers high metal removal when machining titanium is trochoidal milling. Machining either deep or shallow pockets in titanium is known to be a difficult task and as a large proportion of the tool is continuously engaged with the workpiece, cutting forces and heat levels are elevated. Another common problem is uneven chip load per tooth, for example high loads at the point where the cutter has advanced furthest into the... workpiece and lower loads in other areas. Titanium pocket machining also creates a range of issues related to chip evacuation as the cutter fills most of the machined slot width, little room remains for chip evacuation so the chance of re-cutting chips is high. Garr has recognized the potential of trochoidal milling in recent years and has promoted the development of solid carbide end mill cutters in addition to extended flute milling cutters for high productivity when using indexable inserts. Now trochoidal milling can easily be applied using a large variety of Garr’s milling tools. In order to gain maximum performance in this area Garr recommends the use of their VRX. The titanium machining challenge is even greater when the slots to be cut are relatively deep in relation to their width as this machining task increases the difficulty of chip evacuation. Also, when the machined slots are curved rather than straight, chip evacuation becomes even more difficult. Typically, titanium slot machining difficulties make it necessary to run at low feed rates and depth of cut to avoid vibrations and premature cutting tool failure. These enforced conditions lead to unwanted deficiencies in productivity. Even at reduced feed rates, tool life tends to be short when cutting slots. http://www.garrtool.com/doc/pdf/V5.pdf
