Chap 21 machining Flashcards
Single point cutting tool removes material from a rotating workpiece to form a cylindrical shape
turning
Removal of a layer of material from the surface of a workpiece by a rotating cutter
slab milling
Creation of a cavity in a workpiece by a rotating cutter that travels along a certain depth in the workpiece
end milling
Advancement of the tool/workpiece with respect to the workpiece/tool surface in one revolution of the workpiece/tool
feed
Angle between the outside surface of the cutting tool and the imaginary plane that is perpendicular to the cutting direction in a two-dimensional cutting process
rake angle
Undesirable result when layers of material from a workpiece that are gradually deposited on the tool tip in a cutting process; as it grows larger, it suddenly breaks apart only to start reforming again in a cycle of formation and destruction; it is generally undesirable because it changes the geometry of the cutting edge and dulls it
built up edge BUE
Small, individual cutting tools (often of triangular or square shape) with several cutting edges or points {6 or 8 respectively) that are often clamped on a tool holder via a locking mechanism
insert
The rotation of a cutting tool insert in its holder in order to change the cutting edge
indexing
Small piece of material removed from the surface of a workpiece during machining
chip
Angle between the inside surface of the cutting tool and the surface that is being cut in a two-dimensional cutting process
relief (clearance) angle
