Influence of the Trochoidal Tool Path Generation Method on the Milling Process Efficiency

Waszczuk Kamil

Advances in Science and Technology. Research Journal

2020

Vol. 14, no 3

199--203

The article presents a comparison of three trochoidal paths: written by G-Code, generated using the overlays from the machine level, and generated using the CAD/CAM environment. The parameters determining the effectiveness of the process were: maximum achievable feed speed, surface roughness and waviness, cutting forces and cutting temperature when milling NC6 steel (50HRC) using a 10 mm cutter dimeter. The main measurement results include: an increase in the maximum feed speed value by almost 35% when using the A and C paths compared to the type B path and nearly a double increase in surface roughness when using the path generated using the CAD/CAM environment compared to the B path. The most important conclusions was that it is not always possible to machine with the recommended parameters by the tool manufacturer, especially when machining narrow grooves. It was proven that that the use of paths with the displacement described by arcs and straight lines as a trochoidal step over reduces the possibility of milling at high feed rate.

Influence of the Trochoidal Tool Path on Quality Surface of Groove Walls

Waszczuk Kamil, Skowronek Hubert, Karolczak Paweł, Kowalski Maciej, Kołodziej Marek

Advances in Science and Technology. Research Journal

2019

Vol. 13, no 3

38--42

The article presents the results of machining materials in hardened state. In the paper, different trochoidal tool paths are compared with each other and with the conventional milling. The results of measurements show the relationship between tool path, roughness and waviness of grooves wall. The paper also presents pictures of grooves which were made. These results provide comparative material useful in the choice of the best milling strategy to the cutting process.

Slot machining of TI6AL4V with trochoidal milling technique

Patil P., Polishetty A., Goldberg M., Littlefair G., Nomani J.

Journal of Machine Engineering

2014

Vol. 14, No. 4

42--54

Titanium usage for aerospace growing day by day as application of titanium and its alloys covers wide range. Most of the aerospace components made up of wall structure involves lot of pocket slot milling since those components are monolithic components, eliminating need to manufacture multiple pieces for assembly into one final part. The increasing complexity of titanium parts used in aviation industry, increasing demand for productive manufacturing methods like trochoidal milling. This paper aims at evaluating its potential in slot milling for Ti6Al4V component by conducting experiments on 5-axis CNC machine. This study focuses on Productivity, Quality and Machine Tool Dynamics.
