... Abstract Traditionally, the milling process is adopted to machine polygonal geometries from a cylindrical bar on a Sliding Head Turn-Mill Center. In the case of titanium implants, machining helical geometries with polygonal cross sections is time-consuming. However, to meet increasing demand...

... the process is still stable, unlike current methods that detect chatter only after it occurs. This approach was applied to turning in our previous work, and the present work reports the preliminary results of extending its application to milling. While turning dynamics are time-independent, milling dynamics...

... Abstract The stability lobe diagram (SLD) is an important expression way of milling stability prediction result. The SLD obtained by only selecting the most flexible mode fails to predict the chatter if the milling process is dominated by multiple modes. To reveal the relationship between...

... Abstract Vibrations during milling of hard-to-cut materials can cause low productivity, inferior quality and short tool life. It is one of the common issues in the machining of hard-to-cut materials employed in aerospace applications, such as titanium alloys. This paper presents an analysis...

... on the results of the time domain simulation. To verify the proposed method, corner machining experiments with an end mill were conducted. Corner machining is frequently used in industrial, but it is known that chatter vibration is likely to occur. In corner machining, machine tools generate motions...

... of the cutter is the same. Therefore, the cutting forces generated by cutters with different teeth numbers can be predicted based on only one experiment. Thirdly, from the various comparisons, it is concluded that cutter with 2 teeth number is suggested for side milling and cutter with 3 teeth number...

..., it is confirmed that regeneration can be suppressed effectively by the proposed method, resulting in significant chatter stability increase. Low immersion milling experiment verified significant stability and robustness of the proposed variable helix design. Keywords: chatter, regeneration, milling, variable...

... This paper presents a model-based computationally efficient method for detecting milling chatter in its incipient stages. Based on a complex exponentials model for the dynamic chip thickness, the chip regeneration effect is amplified and isolated from the cutting force signal for early chatter...
