提出了一种记录微细电火花加工过程中能量交换总量的新方法。特别是，这种方法允许使用理论模型和实验结果的组合来估计两个电极（工具和工件）吸收的能量的百分比，这要归功于先进的放电测量方法。在Sarix SX200微电火花机床上使用碳化钨工具电极进行了实验活动。特别是，该过程中分析了两种不同的电极形状，三角形和矩形的平行六面体，和两套加工参数。在实验活动执行之后，估计在整个模具下沉过程中发生的能量的总量。从测量实际从工具和工件去除的材料的体积来估计有效地损失到工具、工件和电介质中的能量。初步结果似乎符合文献中提出的，然后评估了几个理论陨石坑模型的有效性。所提出的采集方法的验证，可以使有关的信息的使用，在微细电火花加工过程的模拟能量再分配。
This paper presents a new approach for the recording of the total quantity of energy exchanged during the micro electrical discharge machining (EDM) process. In particular, this approach allows for the estimation of the percentage of energy absorbed by the two electrodes (tool and workpiece) using a combination of theoretical models and experimental results, thanks to an advanced discharges measuring approach. An experimental campaign was executed on a Sarix SX200 micro-EDM machine with a tungsten carbide tool electrode. In particular, the process was analyzed for two different electrode shapes, a triangular and a rectangular based parallelepipeds, and two sets of machining parameters. After the execution of the experimental campaign it estimate the total amount of energy that occurred during the entire die sinking process. The energy effectively lost into the tool, into the workpiece and into the dielectric was estimated from the measurement of the volume of material actually removed both from the tool and from the workpiece. The preliminary results appears to fit those presented in the literature and the validity of several theoretical crater models was then assessed. The validation of the presented acquisition method could enable the use of information related to energy repartition in the simulation of the micro-EDM process.
