Faceplates are used to hold work that is too large or of such a shape that it cannot be held in a chuck or between centers. Faceplates are equipped with several slots to permit the use of bolts to secure the work, so that the axis of the work-piece may be aligned with the lathe centers. When work is mounted off – center, a counterbalance should be fastened to the faceplate to prevent imbalance and the resultant vibrations when the lathe is in operation.
To find the sum of the interior angles of a regular hexagon, we can use the formula:
Sum of interior angles = (n - 2) x 180 degrees
For a regular hexagon, n = 6, so the formula becomes:
Sum of interior angles = (6 - 2) x 180 degrees Sum of interior angles = 4 x 180 degrees Sum of interior angles = 720 degrees
Therefore, the sum of the interior angles of a regular hexagon is 720 degrees.
