Sample preparation from prototype material samples is a critical step in materials science and engineering research. With limited quantities of unique prototype materials, it is crucial to carefully handle and prepare samples for accurate and representative testing and analysis. This involves selecting the region of interest, employing precise EDM cutting or machining techniques to extract the sample. The goal is to maintain the sample's integrity while creating a smooth, round or flat surface for application testing, mechanical testing, microscopy or spectroscopy examinations.
