Video: The Role of Heat in High Speed Machining
In high speed machining of die/mold steels, the heat has a more beneficial effect than the role it plays in conventional cuts.
In high speed machining of hard steels, heat has a plasticizing effect that can benefit the cut. This effect is basic to high speed machining in die/mold applications. In the video from Expert Technical Training, animation illustrates the effect of heat in conventional milling and how this contributes to work hardening, versus the helpful effect of heat in climb milling at faster spindle speeds and feed rates.
Simple process considerations can increase your productivity in milling titanium alloys.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
By using specialized cutter geometry and incorporating smooth finishes with tough coatings, Toolmex Corp., created an end mill well suited to cut aluminum aggressively. This tool called the "Mako" is part of the SharC line of specialized tools from the same company.
