Yes It is common to cut small slopes by WEDM, but it is rare to cut large slopes. The height of 100 5 degrees is already a big slope, so you can cut the workpiece obliquely again. WEDM, also known as low-speed wire-walking, is a kind of NC machining machine tool that uses continuous moving filaments as electrodes to pulse spark discharge the workpiece to generate high temperature above 6000 degrees, remove metal and cut it into workpieces.
