Course Description

Covers how to calculate proper cutting speeds, revolutions per minute (RPM) and feeds for various machine tools and cutting conditions. Introduces how accurately calculating speeds and feeds prior to cutting on the work piece will save time, money, and avoid the waste of materials and tools. Audit available.

Addendum to Course Description

Speeds & Feeds - It is important for a machinist to be able to calculate proper RPM and feeds rather than to rely on a trial-and-error method. Accurately calculating speeds and feeds prior to cutting on the work piece will save time and avoid waste of materials. In this module, you will receive instruction and practice in calculating cutting speeds, RPM, and feeds.

Intended Outcomes for the course

Introduce the student to the formulas and reference materials needed to perform the necessary calculations for obtaining the correct speeds and feeds for the appropriate machining operations.  

This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding:

  • When given reference materials and problems, which require the calculation of speeds and feeds, the student will be able to locate the needed information and perform the necessary calculations to determine correct machine speeds and feeds 80% of the time.  

Course Activities and Design

MCH 125 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.
