4. make precision layouts on the surface plate using precision layout tools, such as the vernier height gauge, angle plates, parallels, and V-blocks;
5. apply basic mathematical formulas for calculating correct speeds, feeds, and data required for precision part layout;
6. evaluate a blueprint to make a manufacturing plan to produce the desired machine part;
7. safely setup and operate a manual lathe to make a 60 degree threaded shaft;
8. safely setup and operate a manual milling machine to make a prismatic part manufactured within the part drawing tolerances and geometrically shaped part;
9. 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;
10. 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.

Textbook(s) (Typical):
Machine and CNC Technology, Fitzpatrick , Career Education; 1st edition, 2004*
*Rationale: This book more completely covers the subject matter taught in Chabot's Machine
Tool Technology program than any other text book we have found. The new edition is due out in the first quarter of 2010. We will adopt that edition if, after review, we feel it continues to meet our needs.
Operations Manual for Machine Tool Technology, Clifford Oliver, Chabot Bookstore*
*Rationale: This book was written by a former Chabot College Machine Tool instructor and is an exact match for the projects, equipment, and operations that are taught in Chabot's
Special Student Materials:
