A. A manufacturing company received an order to machine 800 parts. Using a CNC milling machine, the engineer in charge has the options to do machining at three (3) cutting speeds (100, 300, and 500 m/min) and using three (3) types of cutting fluids/cooling techniques (flood cooling, near dry machining/minimum quantity of lubricant (MQL), and dry machining (without cutting fluid)). After cost estimation on total tool cost and cutting fluid cost (including purchase, handling, and disposal costs), the data in Table Q2 is obtained. You know that there are three (3) pillars/major aspects of sustainability, which are economy. society, and environment. From the data in Table Q2, recommend which type of machining condition to conduct the machining process. Justify your recommendation (10 marks) Machining condition.
