FINAL2 Flashcards
used to make a flat surface at the end of the work piece and perpendicular to its axis.
Facing
removal of material from the outer diameter of a rotating cylindrical work piece.
Turning
also called cutting off.
cutting away a desired length of the workpiece into two or more parts.
Parting
to enlarge a hole or cylindrical cavity made by a previous process or to produce circular internal grooves
boring
process of boring a hole to more than one diameter on the same axis.
counter boring
process of enlarging holes to accurate sizes.
reaming
process of making a whole and usually followed by boring to improves its dimensional accuracy and surface finish.
Drilling
to produce a regularly shaped roughness on cylindrical surfaces.
it provides effective gripping surface.
Knurling
an operation that feed a tool at an angle to the length of the workpiece in order to create a conical shape or reduction in diameter.
Tapering
cutting a narrow groove on the cylindrical surface.
* it can be square, radial or beveled.
Grooving
beveling the extreme end of a workpiece.* used for removing burrs, to protect the end of the workpiece from being damage and to have a better look.* it is essential before thread cutting.
Chamfering
Used a forming tool having cutting edges conforming to the shape required is fed straight in to the work for turning a convex, concave or any irregular shape.
Forming
Filing operation that removes burrs, sharp corners and feed marks from the workpiece.
Filing
After filing, the surface quality is improved by the polishing operation with the help of emery cloth of fine grades.
