COMPOUND MITER
Compound Miter Cuts
You’re installing crown moulding on the upper wall of your living
room. If the wall corner angle is 60° and the spring (crown) angle is
38°, find the miter angle and bevel angle cut.
KEYSTROKE DISPLAY
1. Store the spring angle:
o o 0.
3 8 ß Â
(Spring Angle)
SPRG 38.00°
2. Enter wall corner angle and calculate miter angle:
6 0 Â* MITR 46.84°
3. Calculate bevel angle:
 BEVL 43.03°
4. Display stored spring angle:
 SPRG 38.00°
5. Display entered wall corner angle:
 CRNR 60.00°
*When a value less than 25 is entered as the wall corner angle, the compund miter
function assumes this is the number of sides of a polygon, calculates the wall corner
angle, and displays it first before displaying the miter angle.
