Workholding Devices of Milling Machine

The usual objective of millilng is to produce flat surfaces. This means that a number of ottributes of the lathe, unimportant when turning, become prime considerations when milling. I have already referred to one- the fact that the lathe is deliberately built to turn concave on the faceplate by a very small amount. This means that a large radius flycutter will “interfere” on the  rearward part of  its revolution by. perhaps,0.001 inch or so. There are other reference planes. too. which should be checked.
