dc.description.abstract Machining is a production process using machine tools by utilizing relative movement between the chisel and the workpiece so as to produce a product in accordance with the desired geometric results. Hard materials have abrasive properties and a high hardness value or Young's modulus ratio. As a result of all this, the hard lathe process requires cutting tools that are much harder and less abrasive. One type of chisel that has hardness and resistance to wear is carbide. The aim of this research is to study the productivity of coated carbide chisels used in turning hardened steel and adapt the mathematical model of coated chisel productivity as a fitness function for the simulated annealing algorithm to obtain optimum productivity values. There are 3 fitness functions produced, VMR (max) = 1692.656 – 15.977v – 769.877f + 70.6921a, TL (max) = 117.149 – 0.93665v – 107.831f – 9.9738a, Ra (min) = 2.38654 – 0.01665v + 7.869231f – 0.35385a. By using this fitness function, the best fitness is produced with a fitness value = 432.6339 cm3 with a value of v = 65 m/min, f = 0.15 mm/ rev, and a = 1.5 mm. The highest TL is 25.13 min with v = 65 m/min, f = 0.15 mm/rev, and a = 1.5 mm. This option can be used if there is no urgent work (lots of free time) or if market demand is low. The lowest Ra is 1.92 with v = 65 mm/min, f = 0.15 mm/rev, and a = 1.5 mm. This option is used if we want to get the best quality product, namely with the smallest possible roughness value.
