1.00 Credits
1 class hour Introduces the student to the laws and rules that apply to all oil and solid fuel burning appliances in Maine. Discussions and lectures will be centered around the State of Maine rules book for the installation of oil and solid fuel burning appliances, National Fire Protection Association pamphlets #31 and #211, and portions of the National Electrical Code. Prerequisite: PLH 211 or instructor's permission
-
3.00 Credits
2 class hours, 2 lab hours This introductory course focuses on computer numerical control (CNC) milling machines. This course provides the fundamental technical information in machining systems, positioning and coordinate systems, as well as part programming, program procedures and basic setup and operation of CNC milling machines. Students will write simple programs to perform contouring and hole-making operations for typical CNC milling machines and perform the required setup and operation to produce parts to blueprint specifications in the college's state-of- the-art CNC lab. Emphasis is placed on developing an understanding of typical G and M codes used in modern CNC controls. Students will be required to perform calculations for speeds and feeds for various tooling. Safe work practices and materials handling will be an integral aspect of the classroom and work environment.
-
3.00 Credits
2 class hours, 2 lab hours Designed to provide students with an introduction to CAM software. Emphasis will be on creating 2 1/2 -axis CNC Milling operations: l Facing - regular or irregular profiles, with or without islands and pockets, using conventional, climb and alternating zigzag machining patterns l Pocketing - regular or irregular profiles with an unlimited number of sub-pockets and islands using spiraling, concentric-in or concentric-out patterns, with unidirectional or bidirectional machining to perform climbing or conventional cutting with roughing, wall-finishing and floor-finishing options. l Contouring - profile cutting for roughing, slotting, semi-finishing and finishing straight or tapered walls with constant or variable cutting depths. l Hole making - drilling, boring, tapping and other pointto- point machining cycles. l Spiraling - machining circular pockets and bores with concentric-in and concentric-out cutting as true spiral or tangent arcs. l Library standard tools - develop a tool library to include spot drills, drill, taps, finish end mills and roughing end mills. l Post processing - convert files to standard G&M codes using a variety of posts for use on CNC Milling Machines. Prerequisite: MTT 121 or instructor's permission.

3.00 Credits
2 class hours, 2 lab hours The guidelines for consistent and clear application of dimensions and tolerances are defined by the standards of the American National Standards Institute (ANSI) as written by the American Society of Mechanical Engineers (ASME). The number of companies requiring compliance with national standards is continually growing. This course provides the student with the complete fundamentals of geometric dimensioning and tolerancing (GD&T) concepts as adopted by ANSI and published by ASME. It builds on prior knowledge of blueprints and machined parts and applies that knowledge to "geometric toleranced" drawings. Students will learnthe terminology and definitions of geometric dimensioning and tolerancing and how to apply its concepts. This comprehensive course will prepare students for ASME's GDTP Certification. Prerequisites: MTT 111, DRR 112 or instructor's permission.

6.00 Credits
3 class hours, 9 lab hours This course offers hands-on experience under work-like conditions and in-depth CNC projects that build on skills acquired in MTT 111, PMM 120 and MTT 121. Set-up of CNC machine tools including the selection of tooling, developing custom work-holding fixtures, manual programming techniques, troubleshooting, calculation and input of offsets, and maintaining quality through a production run are developed beyond the introductory level of PMM 120. Training at this level will prepare students for NIMS Machining Level I Certification (CNC Milling & CNC Turning). An integral part of the instruction will include safe work practices and material handling. Instruction will take place in the college's world-class HAAS Technical Education Center. Prerequisite: MTT 121; Corequisite: PMM 122
-
6.00 Credits
3 class hours, 9 lab hours This course offers intermediate to advanced hands-on experience, under work-like conditions and in-depth CNC projects including 3 and 4 axis operations. Manual programming and CAM software will be used to prepare CNC programs for both mills and lathes. Training in manufacturing process improvement will focus on the methods used by leading firms to eliminate non-value added activities from their manufacturing processes. Machine tool probes will be used to establish machine set-ups, inspect cutting tools and measure machined components. Training at this level will prepare students for NIMS Machining Level II Certification (CNC Milling & CNC Turning). An integral part of the instruction will include safe work practices and material HAAS Technical Education Center. Prerequisite: PMM 231
-
3.00 Credits
3 class hours Introduces the origins and development of the American system of government. Special consideration will be given to the United States Constitution, the powers and limitations of the executive, legislative and judicial branches of government, the political process and the policy-making process.
-
3.00 Credits
3 class hours Techniques and processes that lead to effective human interaction both at home and at work are examined through in class discussions and experiential exercises that enable the student to become more aware of the various aspects of human interactions that occur in their daily lives. Classroom focus is on the student's understanding of intrapersonal and interpersonal effectiveness with emphasis on communications, motivation, leadership, personal attitude, and conflict and stress management skills.

3.00 Credits
3 class hours The development of the individual is an exciting process, beginning at birth and continuing through the intricate changes of growth and aging. The study of the life span is also intriguing because each of us, and everyone we care about, is constantly developing. This course therefore includes the biosocial, cognitive and psychosocial domains of human development. Prerequisite: PSY 101
-
3.00 Credits
3 class hours Students will demonstrate mastery of past and current theoretical perspectives on abnormal behavior. The course will evaluate issues relating to classification, etiology, and treatment of basic abnormal behaviors identified in the diagnostic and statistical manual. Case studies will be examined as they relate to various disorders. Prerequisite: PSY 101
