MEC322 - Final Exam| Ques ons and answers |
Updated Rated A+ 2026
Machining
Cu ng ac on that deforms material and forms a chip.
Abrasive Process
Material removed by hard, abrasive par cles (such as Grinding)
Rake Angle
Angle between cu ng tool and chip
Relief Angle (clearance angle)
Angle between cu ng tool and workpart
Turning
Work piece is rota ng and material is removed
Drilling
Tool is rota ng while work piece is stable
Milling
Mul ple cu ng edge tool that is perpendicular to movement of work piece.
Rake Face
Face on the cu ng tool that 'directs flow of newly formed chips'
Flank
Clearance between tool and workpart
Orthogonal Cu ng Model
Where a wedge-shaped tool is used perpendicular to cu ng speed.
Primary Shear Zone
Where the ini al shearing for the work part happens.
, Secondary Shear Zone
Where the chip rubs along the tool and creates fric on.
Chip Breakers
Control the length of a chip. (chip can tangle if piece is too big, so 'Chip Breaker' used)
Con nuous Chip
How: Have duc le materials that can be cut at high speeds and at small feeds and depths
Form: Good surface finish
Buildup Edge (BUE) in Con nuous Chip
High temperature and pressure that causes some parts of the work material to 'adhere' (s ck)
to cu ng edge
Serrated Chip
How: Have difficult to machine materials at high speed
Form: 'saw-tooth' appearance
Discon nuous Chip
How: Bri5le materials at low cu ng speeds
Form: Irregular texture
Forming
Part geometry that is created by the shape of the cu ng tool.
Genera ng
Part geometry that is determined by the feed trajectory of the cu ng tool.
Contour Turning
Creates a contour shape by having cu ng tool NOT parallel to axis of rota on.
Facing (Turning)
Fed radially into rota ng work to create flat surface on the end.
Chamfering (Turning)
