MAE 1351-Exam #1 Questions And Answers With Verified Solutions Graded A+

A blend (loft) requires at least these many profile sketches: - two algebraic or associative constraints - Constraint that define a value of an algebraic expression containing other variables from the solid model as-built drawings - marked-up drawings from a civil engineering project that show any modifications implemented in the field during construction Blind Hole - A hole that does not go completely through the work piece. boring - process of making a hole by plunging a rotating tool bit into a part, moving a rotating part into a stationary tool bit, or moving a part into a rotating tool bit. brazing - method for joining separate metal parts by heating the parts, flowing a molten metal (solder) between them, and allowing the unit to cool and harden. broaching - process of creating uniquely shaped holes and slots using a long, shaped cutting tool that moves along the length of a part in a single stroke when placed against the part Bulk deformation includes - forming (forge, roll, extrude, vacuume) and sheet metal (drawing, stamping, bending) Bulk formation includes - casting, modeling, powder metallurgy, rapid prototyping COTS stands for: - Comercial Off The Shelf crest - top surface or point joining the sides of a threaddatum geometries - points, axes, and planes that do not actually exist on real parts, but are used to help locate and define other features datum planes - planes used to define the locations of features and entities in the construction of a solid model deep drawing - Creating a thin-shelled part by pressing sheet metal into a deep cavity mold Describe how schematic and simplified thread representations appear on a drawing. - schematic shows the threads as a series of lines that are perpendicular to the thread axis. simplified thread shows the major diameter of the shaft and the threads as a dashed line parallel to the thread axis Describe the process and tools used to manufacture internal threads - a tap or a lathe can be used to cut these descriptive geometry - A 2D graphical construction technique used for geometric analysis of 3D objects die - special tool made specifically to deform raw or stock material into a desired outline of a part or feature in a single operation driven dimension - variable connected to an algebraic constraint that can only be modified by user changes to the driving dimensions
