Optimal Inserts for Profiled Turning of Impellers

Article Preview

Abstract:

Processing any kind of parts, requires in our days a focus on obtaining, not only the required characteristics, but a high economic efficiency too. One of the main ways to reduce costs is to reduce processing duration. Starting from profiled turning rotors made by difficult-to-cut materials such as titanium alloys or materials with nickel base, paper analyze the efficiency of processing taking into account all types of inserts available to be used for a given toolholder type. The analysis highlights certain processing features according to the geometric shape and makes a classification based on these performances. The verification of these features is performed with a CAD program on an impeller, using machining characteristics declared by the chosen manufacturer, considering the linear zig method for turning. Regarding the contour turning method, it makes an analysis of the problems caused by the variation of chip length, relative to the maximum cutting depth allowed by tool.
