Measurable Objectives:
Upon completion of this course, the student should be able to:
properly use precision measuring tools, such as the vernier caliper, vernier height gauge, dial test indicator, and various types of micrometers, also optical / video measuring machines;
perform common bench operations, such as filing, sawing, deburring and hand threading;
set up and perform basic drill press, bandsaw, lathe and vertical milling machine operations;
make precision layouts on the surface plate using precision layout tools, such as the vernier height gauge, angle plates, parallels, and V-blocks;
apply basic mathematical formulas for calculating correct speeds, feeds, and data required for precision part layout;
evaluate a blueprint to make a manufacturing plan to produce the desired machine part;
safely setup and operate a manual lathe to make a 60 Degree threaded shaft;
safely setup and operate a manual milling machine to make a prismatic part manufactured within the part drawing tolerances and geometrically shaped part;
offhand grind a High Speed Steel Toolbit to a tolerance of +/- 1 degree for each of the tool’s six major cutting or clearance angles as described in the Machine Tool Laboratory Manual;
measure the parts manufactured and evaluate whether the piece part is acceptable to the print tolerance, geometries and published machining standards like ANSI Y14.5M.

Assignments and Methods of Evaluating Student Progress:
Homework: Sketch the C-Clamp project, draw in the tool and cutting locations, and calculate their X - Y coordinate positions.
Laboratory assignment: Manufacture a complete C-Clamp project and all 6 of the detail parts of the C-Clamp Assembly to published blueprint standards and practices. Verify the thread sizes to a class 3A published in the Machinery Handbook. Maximum Pitch Diameter .3344” and Minimum .3311” Minimum. Inspect the other parts on the Video measuring machine and recreate a “first article” inspection report. Did the part pass inspection? Why?
Laboratory assignment: Offhand grind a right-hand general-purpose lathe cutting tool on the pedal stool grinder with the proper angles specified for cold-rolled steel: Side Relief of ten to twelve degrees, Front Relief of eight degrees, Side Rake of twelve to eighteen degrees, and a Back Rake of eight to fifteen degrees.
