EDM A
Preguntas del test (3)
1What Type of surface finish is the E.D.M Machining process capable of generating?
- AA consistent surface finish, with no discernible 'lay'
- BOnly a very rough finish
- CA surface finish composed of many irregular scratches
- DOnly a very smooth finish that is unacceptable for any mould cavities
2What type of clamping pressure is used when holding parts that are to be EDM machined?
- ANo clamping equipment required; the EDM process does not put any pressure on the workpiece
- BLight pressure, as the machine operation does not subject the work piece to great pressure
- CMedium pressure, to counteract the high pressure of the dielectic fluid and the electrode
- DHeavy pressure, to ensure that the downward cutting forces exerted by the electrode do not move the workpiece
3What is the function of dielectic fluid?
- AIt creates a smooth surface finish by eroding the particles away
- BIt cools the hydraulic cylinders that control the ram head
- CIt acts as an insulator and flushes away eroded particles
- DIt lubricates the table feed mechanism and cools the work
