Ultimately, this is a technological world, hand operated mechanical tools used to take very long to accomplish a task and it was difficult on complex to perform those tasks. These days, just a program and everything is done in minutes. I wonder what the future portends.

Hyatt - it is really unimaginable. People use to suffer a lot before discovery of automation. It will make the manufacturing industries to grow significantly. The trends are heading towards full automation.

WHAATA GOOPS! I went for some coffee and came back to this! Thanks guys!

I also believe EDM machine is the best CNC machine tool, it produces excellent finishes with very insignificant error margin. But I respect the opinion of every last one of you!

Oh - another thing: the finishings of EDMs: they a extremely fine finish product as compared to other machining methods. It eliminates the need for after work finishing procedures.

never forget that EDM machining is slow compared to other types of machining.

I agree with you but its advantages outweigh the disadvantages. You have to know that everything have its limitation and we evaluate it as the best when limitation is minimal.

I am surprised no one has talked about the process. EDM machining uses graphite which is favorable for these metal cutting. It is not affected by high temperatures, cheaply available and available in large qualities and resistant to wear.

CNCs machine can be used continually for twenty four hours a day and three hundred and sixty five days a year. Imagine if it was mechanical methods they could have broken down due to mechanical malfunctions. It would be worse is it was done manually by hand.

CNCs FTFY.
Some small routers can be operated by less skilled and untrained people unlike manual machines like lathes, milling machines among others which need skilled and trained personel.

its actually true. Remember also that the CNC machine operator requires little industrial training and personal skills to manage and supervise many machines. Years back engineers used required many years of industrial training to operate machines like lathes, milling machines and other many manually operated ones. But, now they have lost the valuable acquired skills at the present due to introduction of these simple procedures.
