STUDENTS WITH SPECIAL NEEDS:
If you are a student with special medical needs, please inform me as to how I can best assist
you. All information will be considered confidential.
If you are a student who needs special ADA-related accommodations, please inform the DCC
ADA Coordinator at 434-797-8441. All information will be considered confidential
CELLULAR PHONES:
Cellular phones will be permitted in class during lectures only if they can be set on
VIBRATE. Turn them off otherwise. The class is not to be disturbed by ringing cell phones!
Students will not be permitted to leave the class during tests and quizzes should their phone
ring. Doing so will result in the student submitting the test or quiz at that time. Cell phones
will be permitted during lab hours.

TEXTBOOKS, OTHER REFERENCE MATERIALS:
Machine Tool Practices – Kibbe, Neely, Meyer, White – ISBN – 0-13-118896-8
EQUIPMENT:
1.
You are required to wear eye protection (ANSI Z87.1 CE approved) at all times
when in the shop.
2.
It is strongly suggested that you wear ear protection as well.
3.
It is recommended that you not wear contacts while in the shop and NEVER wear
contacts when welding!
4.
You may bring your own hand tools for use in the lab. (Scales, scribers, various
wrenches, center punches and squares) They are your sole responsibility. There
are a limited number of tools designated for student use in the lab.
Attendance Requirement:
1. Each student is expected to attend all lecture and laboratory classes, since demonstrations and
assigned projects will be done on the machines in the shop.
2. Quizzes will be given at the beginning of the period on lecture days. Students tardy to class
may miss these quizzes. They may not be made up. Quizzes given during class must be
completed during the class period.
3. Students with perfect attendance and less than 2 tardies will earn 3 percentage points that will
be added to the final grade. Leaving lab early without instructor approval will be counted
as a tardy.
4. Students will work with a partner on lab activities. For this reason it is imperative that both
students work on projects together. Each lab missed by a lab partner when working on the
lathe will cost the absent student 10 points off the lathe project grade. Should the student
miss 3 labs during the lathe project, the student will be expected to make the project
individually. Should a student miss a lab day when using the mill, the student will loose 50
points off the mill project grade. The student will have the option of completing this project
individually to avoid the grade reduction.
