Inconel 718 is a highly valued material in the aerospace and nuclear industries due to fact of its exceptional properties. However, processing this quite difficult, especially through machining processes. Machining results rapid tool wear, even when low removal rates are considered. In study, instrumented turning experiments were employed evaluate machinability alloy using PCBN tools while asse...

In order to improve the tool life and micro-hole machining quality, H-shaped chisel edge micro-drill (HCE-MD) was developed in this paper. The HCE-MD characterized by inner formed through thinning. micro-drilling process, can perform positive rake cutting, so area of workpiece extruded cutting with a negative angle is reduced. Based on this, distribution near corner improved. Then, fabricated s...

Abstract One of the main limits productivity during cutting processes is occurrence regenerative chatter. Due to these self-excited vibrations, load capacity machine components, tool as well performance cannot be fully utilized. There are several methods stabilize milling process. use increased process damping, which results from contact tool’s flank face and workpiece. The wear land naturally ...

Titanium alloys are the difficult to cut metals due their low thermal conductivity and chemical affinity with tool material. Since vibration is a replica of wear surface roughness, present study has proposed methodology for estimating roughness based on milling Ti-6Al-4V alloy using cemented carbide mill cutter. Experiments conducted at optimum levels cutting speed, feed per tooth, depth cut, e...

This study focuses on milling under sustainable cutting conditions of ST52 steel, frequently used in the manufacturing industry. steel is a good candidate as workpiece because it inexpensive and readily available. To achieve conditions, zone minimum quantity lubrication technology was during processing. The experiments three speeds (120-180-240 m min-1), feed rates (0.12-0.18-0.24 mm rev-1), co...

Abstract. Higher cutting force and its temperature with faster tool wear are the causes of higher production costs lower machining efficiency. In this paper, help electrical discharge (EDM) laser technology, texture holes implemented on rake face principal flank tool. The force, friction characteristics surface roughness compared micro-textured processing technology system non-textured inner co...
