I am currently doing an apprenticeship to be a machinist, and as a requirement we were issued with a set of questions to write answers to. I am finding many of the questions particularly difficult to answer.
Part of the reason for this is (I think) that I work for a manufacturer of Tungsten Carbide wear parts, and as a result don't get experience with the full range of EDM capabilities and requirements.
Does anyone know of any sources of information I can look at in order to answer these questions? Some examples:
"K18 Outline the different types of electrodes/wire, and the material conditions determining their use"
"K19 Describe selecting the correct grade and type of electrode/wire for the materials and profiles being machined"
"K27 Explain how the various types of materials will affect the feeds and voltage that can be used"
"K28 Explain the application of dielectric fluids with regard to a range of different materials"
I don't know the answer to these because I don't get to machine anything but Carbide.
