Overhang length effect during micro-milling of

2019-3-12  Micro-milling process is influenced by some factors such as machining parameters and tool properties. Overhang length in the milling affects the tool wear and tool life. It is known that a longer overhang length most likely results in a higher vibration and because of vibration, the tool life reduces, and surface quality becomes poor.

Analysis of force patterns and tool life in milling ...

The paper describes the practical effects of the operating parameters in the milling operation. Experiments have been conducted to measure cutting force and tool life under dry conditions. Based on the experimental results, three mathematical models have been developed: Force, TLife and Force/TLife. Further analyses have been conducted on the cutting force patterns: seasonal pattern and ...

The influence of machining parameters on surface

2021-6-17  The value of surface roughness increased with the increase of tool diameter. The tool diameter of 6 mm achieved surface roughness higher than 4 mm tool diameter. The value of surface roughness decreased with increasing spindle speed. Spindle speed at 24000 rpm were able to produce the best surface roughness in milling operation.
