Green improvement in machining process could come from manufacturer initiative. But, they usually doubt to apply this improvement because it will influence product quality and production cost. To analyse this influence, the relationship between green, quality, and cost objectives should be modelled. Using axiomatic quality principle, this research has been developed some methodology which is axiomatic green. This approach is started by mapping the relationship between all of the objectives defined using axiomatic tree diagram. Then, an experiment is conducted to define the relationship between relevant response and control variables. Finally, in the optimization phase, analytical techniques used to generate and optimize non-linear programming (NLP) formulation. The solution generated by this model should be implemented as the green improving solution. In this research, axiomatic green methodology was implemented to improve production process to be greener in a manufacture in Indonesia. This manufacture has an initiative to minimize the waste that is generated from coolant using in machining process. Coolant-type cutting fluid is a liquid that is applied directly to the wet machining operation to improve cutting performance. This liquid seems to be most effective at relatively high cutting speed when heat generation and high temperatures are problems. In the other side, coolant can also cause some environment problems that are generated by fluid disposal activity. Dry machining is the extreme opposite of the wet machining where there is no coolant used here. This strategy will eliminate the fluid waste, but can decrease cutting performance. So, dry machining will be feasible implemented if its performance is equal or better than the minimum standard used by manufacturer and customers. As a result, machining parameters must be adjusted when this strategy will change another one before. By using this proposed methodology, manufacture is possible to be greener with using the parameter of Toki tool type with the angle of 103.4904°, machining feed rate of 0.1608 mm/rev., and coolant debit of 0.3194 litre/min which is decreasing about 3.6806 litre/min from the existing condition. This solution not only reduced environment impact, but also made the process more efficent with cost reduction of 59,06 rupiahs.
