A method of sampling a multi-layered material and a micro-sampling tool are described. The sampling method includes penetrating a top surface of a material in a component of interest with a micro-cutting tool to a predetermined depth sufficient to include each layer of the multi-layered material and a portion of the base, without cutting through the full depth of the base, undercutting from the depth of penetration through the base to define a micro-sample of the multi-layered material, and removing the micro-sample with each layer of the multi-layered material intact. The micro-sampler includes a cutting tool calibrated to cut to a depth no greater than 2 mm, and in some aspects, no greater than 200 microns into a multi-layered material, the material having a top surface and a metallic or ceramic base and a container for removing and storing a micro-sample cut from the material with each layer of the multi-layered material and a portion of the base intact.

An electrical discharge machine which is less likely to be used in a high risk state. This electrical discharge machine is provided with an intra-setting modification display control unit that, when a risk level corresponding to a setting content directed by a user is higher than or equal to an alert-causing threshold value, displays an intra-setting modification alert-causing display, and a post-setting modification display control unit that, if the state in which the risk level is higher than or equal to the alert threshold value continues, displays a post-setting modification alert-causing display at predetermined time intervals.
