Course Description

Covers setup, applications, and operations of boring on the lathe. Introduces the commonly performed operation of boring on various types of turning machines used to produce part features to print specifications. This course is also offered as APR 190M; a student who enrolls in this course a second time under either designator will be subject to the course repeat policy. Audit available.

Addendum to Course Description

Boring on the Lathe - Boring is the operation of enlarging and truing a drilled hole. A bored hole is always held to a closer tolerance than a drilled hole. It is also concentric with the center line of the work piece. Boring a second hole that is larger than the first but concentric with it, is called counterboring. A tapered hole can also be cut using a taper attachment. In this packet, you will learn how to bore and cut a tapered hole on the lathe.  


Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Safely and accurately turn a piece to print specifications using the setup methods and proper tools used for boring operations associated with the lathe machine.

Course Activities and Design

MCH 190 will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.

Outcome Assessment Strategies

POLICY - Student performance measurements are based on established industry standards. The various areas of study during the course will be evaluated by a variety of activities. Typical of those activities are the following;

1. READING ASSIGNMENTS - Information sheets, textbooks, journal articles and the learning resource center are potential sources of information that the student will reference as directed in the modules identified in the introduction. 

2. PRACTICE - Completion of tasks and projects identified in the reading assignments, information sheets, journal articles and textbooks. Students are required to complete practice activities with 100% competency.

3. SELF-ASSESSMENT - Checking and evaluating the students understanding and knowledge gained through the reading assignments and practices typically done through a practice evaluation.

4. LAB ACTIVITIES - Participation in structured laboratory exercises with the emphasis on developing skills or increasing expertise in the areas of study identified in the module packets.

5. FINAL ASSESSMENT - An assessment in the form of a written exam and/or practical application that addresses the subject areas identified in the module packets. Students are required to complete final assessment activities with 85% competency.
