2.	PREREQUISITE:	MAC 141

3.	RESOURCES NEEDED:
	TEXT:
	SUPPLIES:	Paper, pencil, and calculator Modern Metal Cutting
4.	COURSE DESCRIPTION:
5.	COURSE GOAL:	Provides transitional information between conventional machining applications and the typical applications found in Computer Numerical Control Machining. Topics may consist of Numerical Control Systems, The Cartesian Coordinate System, High Efficiency Tooling Applications, Objectives of Numerical Control, Calculating Speed and Feed Rates, Defining and Calculating Tool Motion, Fixturing Requirements, Basic Program Structure, Programming Codes, and Basic Conversational Programming. Operations of NC machines will be required.

6.	COURSE OBJECTIVES:
	By the end of the course, students will:
	(A)	Provide a transitional base that derives from conventional machining operations to operations consisting of numerical control technology.
	(B)	Provide fundamentals to CNC machining operations and applications.
	(C)	Identify NC controls and functions on a CNC machine.
	(D)	Demonstrate the basic concepts of CNC programming.
	(E)	List the factors that influence the selection of a NC machine.
	(F)	Identify the correct process plan and tooling selection.
	(G)	Develop a manual program to run a NC machine.
	(H)	Demonstrate competency to run a fixtured part using a NC program.

7.	EVALUATION PROCEDURES:
	Semester grades will be based on the following criteria:
		Written Average	25%
		Project(s)	40%
		Participation Grade	20%
		Subjective Grade	15%
	Written Average: Tests, quizzes, worksheets, reports, etc. All written assignments will be evaluated according to the following scale:
		Grading Scale Raw Score Range	Letter Grade
		90 to 100	A
		80 to 89	B
		70 to 79	C
		60 to 69	D
		0 to 59	F
	Projects Average: At the end of each semester the assigned projects will be evaluated according to the following criteria:
		Process Planning	20 points
		Complexity	20 points
		Accuracy	30 points
		Workmanship	30 points
	Participation Grade: This course requires everyone to participate. Everyone is expected to do so constructively everyday!
	Subjective Grade: At the end of each semester the instructor will submit a grade for each student’s work ethic that will be a reflection of the following:
	Working habits Safety habits Care of tools and equipment Ability to follow procedures Teamwork Attendance

Special Remarks:
1.	Attendance: College policy states that students may be dropped from enrollment when absent 20% of the scheduled class meetings. If enrolled from the beginning of the term, 15 hours will usually constitute 20% of a four-credit semester course which meets five hours per week. Reinstatement procedures are described in the PCC catalog.
2.	Tardy Policy: A student who is late three times (enters classroom after the instructor has taken roll) will be charged with one full absence unless the student can provide valid reasons for one or more of these tardies.
3.	Assignments/Missed Exams: It is the student's responsibility, whether present or absent, to obtain all material presented and to complete all course assignments. If prior arrangements are made or extenuating circumstances exist, makeup of tests may be allowed. Late homework papers will not be accepted unless those same extenuating circumstances exist. Makeup of quizzes is to be at the instructor's discretion.

8.	COURSE OUTLINE:
9.	METHODS OF INSTRUCTION:
	To be successful in this course, students are expected to participate in discussions, readings, in-class writing, and peer review activities. The instructor may assign point values to such activities.
10.	ACADEMIC INTEGRITY:
	The very nature of higher education requires that students adhere to accepted standards of academic integrity. Therefore, Pueblo Community College has adopted a policy of academic conduct as described in the Student Handbook. Violation of academic integrity may be defined to include the following: cheating, plagiarism, falsification and fabrication, abuse of academic materials, complicity in academic dishonesty, and personal misrepresentation. It is the student’s responsibility to be aware of the behaviors that constitute academic dishonesty. Sanctions for violating the standards of academic integrity may include warning, probation, suspension, and/or failure of the course or assignment at the discretion of the instructor.
11.	ADA NOTICE:
	Students who have a documented disability may be eligible to receive accommodations for this class. Please contact the Disability Resources Center at 549-3446 for further information.
