A novel concept named sustainable development has come to be considered important to prevent the intensification of climate change. Thus, there have been many reports about the environmental load of consumer goods such as home electronics, car electronics, and so on. However, there have been few reports about the environmental load of industrial goods. Specifically, there has been no report dealing with the environmental load of compact five-axis controlled machine tools and how to use linear-axes and rotational-axes in them.

Then, a suitable end-milling process to reduce the power consumption with a compact five-axis controlled machine tool equipped with an automatic idling reduction servo system by using the developed formula have been discussed. As a result, the combined method of downsizing the machine tool, using suitable control axes, and equipping the machine tool with an automatic idling reduction servo system is found to be effective in reducing the power consumption in a manufacturing process.
