“…Parameter-parameter proses bubut seperti kecepatan potong, gerak makan dan kedalaman potong yang digunakan mempengaruhi sifat mampu mesin dari suatu material [3]. Jika suatu produk hasil dari proses bubut memiliki kekasaran permukaan rendah, gaya potong yang digunakan selama proses pemesinan rendah dan tingkat keausan pahat rendah, maka material tersebut dapat dianggap memiliki sifat mampu mesin yang baik.…”

Every production process always needs to produce high quality with high productivity. However, in machining processes, qualities such as surface roughness and productivity such as material removal rates have different characteristics. Surface roughness has the quality characteristics smaller the better, while the material removal rate has larger the better. Therefore, determining the combination of lathe parameters is very important to get optimal results. A study has been carried out to determine the combination of lathe process on ST 60 material with an environmentally friendly cooling method to minimize surface roughness response and maximize material processing rates simultaneously. The coolant (cold soluble oil and air pressure), spindle rotation (550 rpm, 700 rpm and 1200 rpm), feed motion (0.053 mm / rev., 0.103 mm / rev and 0.161 mm / rev) and depth of cut (0.125 mm, 0.25 mm and 0.5 mm) were used as process parameters. The tool used in this study is a CNMG insert tool with a 0.4 mm corner radius. The experimental design was determined using the Taguchi method in the form of orthogonal matrix L 18 (2 1 x3 3). The optimization method used is the grey relational analysis. The results showed that an optimal surface roughness response and material removal rate obtained by setting the coolant process at level 1 of cold soluble oil, spindle rotation was set at level 3 at 1200 rpm, feeding motion was set at level 3 of 0.161 mm / rev. And the depth of cut is set at level 3 of 0.5 mm.

Magnesium alloys serve as excellent substitutes for materials traditionally used for engine block heads in automobiles and gear housings in aircraft industries. AZ31 is a magnesium alloy finds its applications in orthopedic implants and cardiovascular stents. Surface roughness is an important parameter in the present manufacturing sector. In this work optimization techniques namely firefly algorithm (FA), particle swarm optimization (PSO) and artificial bee colony algorithm (ABC) which are based on swarm intelligence techniques, have been implemented to optimize the machining parameters namely cutting speed, feed rate and depth of cut in order to achieve minimum surface roughness. The parameter Ra has been considered for evaluating the surface roughness. Comparing the performance of ABC algorithm with FA and PSO algorithm, which is a widely used optimization algorithm in machining studies, the results conclude that ABC produces better optimization when compared to FA and PSO for optimizing surface roughness of AZ 31.

In this work, cyclic expansion-extrusion process in the same plane and cyclic expansion-extrusion process in two orthogonal planes have been employed, and the isothermal finite element simulations of both processes have been carried out. The equivalent plastic strains of AZ80 magnesium alloy billets produced by cyclic expansion-extrusion process in the same plane and cyclic expansion-extrusion process in two orthogonal planes were analyzed. Furthermore, the distinction between the accumulated equivalent plastic strains of both processes was also explored. The AZ80 magnesium alloy samples machined from the deformed billets were tested by tensile test machine, hardness tester, and optical microscope. This work also discussed the relationships between the microstructure and mechanical properties of deformed billets. The research results show that the average equivalent plastic strain of deformed billet is larger caused by two-pass cyclic expansion-extrusion process in two orthogonal planes than that by two-pass cyclic expansion-extrusion process in the same plane, and furthermore, the deformation uniformity after two-pass cyclic expansion-extrusion process in two orthogonal planes is far superior to that after two-pass cyclic expansion-extrusion process in the same plane. Cyclic expansion-extrusion process in the same plane can partly refine the grain size of annealed alloy from 190 to around 10 mm; however, cyclic expansion-extrusion process in two orthogonal planes can substantially refine that from 190 to approximately 3 mm. Two-pass cyclic expansion-extrusion process in the same plane can significantly improve the Brinell hardness of annealed alloy from 61.5 to 88.5 HB. Similarly, two-pass cyclic expansion-extrusion process in two orthogonal planes can also obviously improve that from 61.5 to 86.6 HB. Ultimate tensile strengths via two-pass cyclic expansionextrusion process in the same plane and cyclic expansion-extrusion process in two orthogonal planes increase by 60 and 40 MPa than the annealed alloy, respectively. With the identical strain accumulation and deformation temperature, cyclic expansion-extrusion process in two orthogonal planes might look to be attractive when compared with equal-channel angular pressing for improvement of ultimate tensile strength and hardness as well as for grain refinement.
