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

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 PATH TYPE ON SELECTED TECHNOLOGICAL EFFECTS IN THE TROCHOIDAL MILLING

Article presents basic informations about machining materials in hardened state – especially it describes method so called hard milling. Paper talk about strategies and methods in hard milling, describes trochoidal milling, its advantages and disadvantages. Also presents research methodology and effects which concerned determination of tool path impact on selected technological effects after trochoidal milling of the groove

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

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
