Addendum to Course Description

Text:

Mathematics for Machine Technology by Smith, published by Delmar, 6e Edition, ISBN: 1-428-33656-7

Intended Outcomes for the course

Upon successful completion of this course students will be able to:
1. Use sine, cosine, and tangent and functions to determine coordinates of a part to be machined.

2. Communicate technical information to coworkers, clients, and/or engineers.

Course Activities and Design

 MCH 130 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

The final grade will be calculated from the average of a mid-term and a final exam.  The two exams present questions based on the exercises assigned in the class.

Course Content (Themes, Concepts, Issues and Skills)

Machine Shop Math / Trigonometry consists of the following modules:
Module 1 – Fundamentals of Plane Geometry – Plane Geometry is the branch of mathematics that deals with points, lines, and various figures that are made of combinations of points and lines.

Module 2 – Applying Shop Trigonometry - Most of the trigonometric relationships used by machinists are based on the right triangle. The right triangle formulas we used previously dealt with the length of the sides only. Trigonometry formulas deal with both the sides and the angles.

Related Instruction

Computation
Hours: 65

Use sine, cosine, and tangent and functions to determine coordinates of a part to be machined.
 

Through direct instruction students practice

  • Right triangle trig using Pythagorean theorem, Sin, Cosine, and Tangent functions.
  • Some obtuse and acute triangle trig using the law of sins.
  • Students are given blue prints of machine parts that require the use of trigonometry to determine bolt hole patterns and how to locate x and y coordinates.

Communication
Hours: 10

Students will be able to communicate technical information to co-workers, clients, and or engineers

  • Technical communication skills are practiced as students need to communicate industry specific questions related to higher level math.
  • Students learn to ask specific questions related to their current problem by defining the case and what they need to complete the issue at hand.
