A good design drawing can indicate all the details needed to produce a mechanical CNC milling part in an easy way. Because there is no large space on a drawing to contain all the text to illustrate the image, abbreviations, and symbols are often used in engineering drawings to communicate the characteristics of the product to be manufactured.

The indication of surface roughness values in the surface finish symbols are shown the figure A. a) If the surface roughness is obtained by any production method other than machining, the value of surface rough necessary say,12.5μm is indicated in the basic symbol as shown in figure B. b) If the surface roughness is obtained by removing the ...

Unfortunately, normal machining methods like turning, milling or even grinding can not meet this requirement. Therefore, superfinishing processes like lapping, honing, polishing, burnishing are being employed to achieve and improve the above- mentioned functional properties in the machine component.

Grinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.
