Angles

Describe how points can be located using arcs and angles.

 

 

 

Triangles

Relate the use of Pythagorean relations to machine tool operations, especially in layout and location of points.

 

 

 

Circles

Define the terms that apply to using the circle to find points in layout (Example: arcs, sections, cords, radius, circumference, etc.).

 

 

 

 

Use other geometric figures inscribed in the circle to locate multiple equal-spaced points on the circumference of a circle.

 

 

 

Geometric construction

List uses of geometric principles in machining.

 

 

 

 

Use geometric construction to find center points, divide angles, construct right angles for layout, and to find the center of a circle or arc.

 

 

 

Applications

Lay out workpieces using geometric applications.

Right angle trigonometry

Explain how, knowing any three parts of a triangle, at least one of which is a side, a triangle can be constructed.

 

 

 

Functions

Define the six trigonometric functions.

 

 

 

 

Explain the use of trigonometric tables.

 

 

 

 

List uses of trigonometric principles in machining.

 

 

 

Cartesian coordinate system

Explain the Cartesian system, how it applies to machine operations, and how to determine the "Z" axis on a machine.

 

 

 

Applied computations and calculations

Calculate the angle to a given function.

 

 

 

 

Find the function to a given angle.

 

 

 

 

Compute the third angle when one angle and one side of a right triangle is given.

 

 

 

 

Determine a point when an arc and an angle is given from a reference point.

 

 

 

Applications

Lay out work pieces using geometric and trigonometric principles.
