This study focuses on optimizing the use of a coolant pump to clean the CNC machine holder while conserving electrical energy. Coolant pumps serve several functions, including cleaning, lubrication, and cooling. There are three types of cooling pumps available for CNC machines such as shower coolant, through spindle coolant, and bed flushing coolant. The bed flushing coolant pump is responsible for cleaning the engine mount of metal scraps. However, this pump is always running, even when the machine is on standby or not in production activity, leading to unnecessary energy waste. The goal of this research is to improve energy efficiency by optimizing the bed flushing coolant pump with TRIZ design analysis. The approach involves adding a timer-based adaptive program to automatically turn off the bed flushing coolant pump 60 seconds after the production process is complete or when the machine is not in operation. Based on the six-month implementation, there has been a significant saving of electrical energy in the CNC of 936 kWh, which equates to a reduction in energy consumption of 12.5%. © 2024 IEEE.
