Trepanning is a method of hole drilling which leaves a. Trepanning is a drilling process that leaves a core. Machining a material removal process in which a sharp cutting tool is used to mechanically cut away material so that the desired part geometry remains most common application. Generally speaking, laser machining processes include laser drilling, laser cutting. Pdf a versatile laser trepanning system has been designed and. However, machining processes inevitably waste material in the form of chips, production rates may be low, and unless carried out properly, the processes can have detrimental effects on the surface properties and performance of parts.

We combine trepanning with additional machining processes such as honing to produce extremely precise internal diameter dimensions with surface finishes of ra 32 and finer. In many cases, trepanning is meant to be a roughing operation to be honed for finish, or machined further. Trepanning machining is used to produce the following features and parts. Furthermore, the taper angle for the awjm, relative electrode wear rate for edm, burr height and burr thickness for microdrilling, flank wear for microturning process, machining time for micro.
