Summary Due to high demand in engineering materials especially with high strength to weight ratio and advantageous material properties such as wear resistance and thermal stability or high entropy. This essential parametric enhancement has led to the development of Multi Component High Entropy Alloys (MCHEA). It has been proposed in this study to investigate the machinability characteristics of MCHEA. The MCHEA are usually amalgamation with multiple elements such as aluminium, cobalt, manganese, nickel, chromium and titanium with their individual concentrations ranging from 5-35% overall. The experimental design consists of basic characterization of the material and conducting machinability trails-milling. The basic material characterization consists of evaluating bulk hardness, microstructural image generation, microhardness and chemical composition using spectrometry. The milling trails are conducted using 2 flute, 30º helix ball nose solid carbide end-mill cutting tool with combination of cutting parameters such as constant cutting speed, 30 m/min; varied feed, 0.01 mm/tooth and 0.02mm/tooth; depth of cuts, 1.5 and 3 mm and coolant on. The outputs obtained from the machining trails are subjected to analysis such as cutting force. In addition, the surface roughness of the material is evaluated using 3D optical surface profilometer. Similarly, the solutions to alleviate the drawbacks are also exemplified during machining of MCHEA.
