3. How to make machining conditions
EDM machining conditions are made depending on the purpose of machining. The appropriate machining condition varies according to the machining content such as "bottomed machining", "through-hole machining", "rough machining", "finishing", and so on.
1) Machining condition suitable for "bottomed machining"
Because a shape is processed with a small number of electrodes in case of "bottomed machining", machining condition of low electrode wear ratio is required. In addition to lowering "peak current level", "τon (tau on)" is lengthened.
2) Machining condition suitable for "through-hole machining"
In "through-hole machining", "electrode wear ratio" is not important and the machining condition that attaches great importance to "removal rate" is required. In addition to shortening "τon (tau on)", "peak current level" is heightened.
3) Machining condition suitable for "rough machining"
In "rough machining", machining condition that attaches great importance to "removal rate" than "machining surface roughness" is required. In addition to lengthening "τon (tau on)", "peak current level" is heightened.
4) Machining condition suitable for "finishing"
In "finishing", machining condition that attaches great importance to "machining surface roughness" than "removal rate" is required. In addition to shortening "τon (tau on)", "peak current level" is lowered.
