GENERAL DESCRIPTION OF SUBJECT MATTER FOR EACH LECTURE/DISCUSSION

Topic	General Description of Subject Matter
Shop Safety	Explain why it is important to develop safe work habits. Dress in proper safety equipment and clothing for a machine shop. Recognize and correct unsafe work practices. Apply safe work practices when employed in a machine shop. Select the appropriate fire extinguisher for a particular type of fire.
Introduction to CNC Machining	Describe the development of CNC technology. List advantages and disadvantages of using CNC technology. Describe the features of CNC milling. Compare the characteristics of various types of CNC turning Machines. Identify safety guidelines for CNC machining processes. Summarize the use of the Cartesian and polar coordinate systems in CNC technology. Contrast the two types of motors that are commonly used to drive CNC machines.
CNC Programming Basics	Explain the process of planning and developing a CNC program. Describe three methods of generating CNC code. Summarize the use of CAD and CAM software in CNC programming. Classify the types of codes used in the ANSI/EIA 274D code format. Identify commonly used CNC modal commands.

Regular and punctual attendance is required of all students classes for which they have registered. Students absent (excused or unexcused) for 15% of their classes or more may receive an “F” or be dropped from the course. Coming to class late or leaving early will count as ½ of an absence, coming in late or leaving early twice will count as one absence.  All absences are unauthorized unless the student is absent due to illness or emergencies as determined by the instructor.  It is the student responsibility to provide documentation as to the emergency for approval and judgement by the faculty member.  Approved sponsored activities are the only absences for which a student may not be held liable and only when providing notification prior to the absence.  Valid reasons for absence, however, do not relieve the student of the responsibility for making up required work.  Students are not allowed to make up an examination missed unless approved by the instructor. A student that is compelled to be absent when a test is given, will petition the instructor, in advance, for permission to take the exams given during the course at another time. Required work not completed by due dates will not be allowed to be turned in without instructor approval. Class participation in assignments and exams will be used to determine regular attendance for online students.

 

Last day to Withdraw

The last day to withdraw from a course with a “W” is November 1st.

COVID-19 Specific Syllabi Statements Fall 2021

 

Syllabi statement regarding potential Conversion of Onsite Classes to Online/Remote Format: North Central Texas College students should be aware that in the event of a college closure due to COVID-19 or other health related crisis, onsite classes will be converted to an online/remote format. Students should plan ahead to ensure they have access to the computer equipment (either PC, MAC, or tablet), webcam, and internet connectivity to continue their classes in an online/remote format. Please read all your official North Central Texas College student emails as the transition from onsite to online/remote might require a reorganization in your personal situation. Students will be granted a 72-hour transition and grace period. Online classes will continue as scheduled without disruption. Contact your Instructor as the situation arises. These policies and procedures were updated on July 27, 2021 and are subject to change as conditions change.

 

Syllabi Statement Regarding Face Coverings: Per the North Central Texas College guidance on face coverings on campus, in the instructional setting, faculty and students are not required to wear face coverings, such as masks or face shields. In May, Texas Governor Gregg Abbott released an Executive Order prohibiting Government entities from mandating the use of masks. As a political subdivision of the State of Texas, NCTC will follow the Governor’s Executive Order for Government entities and effective immediately NCTC is no longer mandating the use of masks while on campus. This order does not mean that you cannot choose to wear a mask, rather it is no longer allowed to be mandated. These policies and procedures were updated on May 19, 2021 and are subject to change.

 

Return to Standard Attendance Protocol for Face-to-Face Meetings: In spring 2020, we faced an unprecedented situation in which all of us had to be flexible and make prudent decisions in the best interest of our families, our campus, and our community. In light of this, North Central Texas College is temporarily establishing the requirement that faculty keep records of student attendance for face-to-face course meetings as well as a documented seating chart. In addition, students who are sick or need to quarantine should not attend classes. Students will not be required to provide formal documentation from a health care provider and will not be penalized for COVID-19 related absences when proper notification to campus health officials is made in accordance with the guidelines stated below.

 

Faculty will:

 

• Notify students about important course information and delivery changes through Canvas and campus email.

 

Students should:

• Provide notification to campus officials if they have tested positive for COVID-19 or have to quarantine so we can confirm reported absence with instructors, monitor, and assist the campus community.
• Notify instructors in advance of the absence.
• Connect with that class through Webex if the class session is being transmitted in a hybrid fashion.
• Keep up with and/or make up missed classwork or assignments.
• Submit assignments digitally through Canvas or other means as announced by your instructor.
• Work with their instructors to reschedule exams, labs, and other critical academic activities described in the course syllabus.
• Check Canvas and campus email daily to receive important announcements pertaining to the course.

During the fall 2021 semester, faculty with face-to-face meetings will establish assigned seating/work stations to facilitate roll-taking, and, if necessary, contact tracing. Additionally, we ask all members of the College community to be attentive to their health, and safeguard others, by following the CDC’s guideline to “stay home when you are sick.” You should stay home if you have symptoms. More information on what to do if you are sick is available at the CDC’s website.
