Abstract: Programmable bevel jig which is simple to use and can easily be attached to a workpiece to produce various types of complex bevels. Multiple angles and angle tolerances can be programmed into the jig, and then selected during machining. Different color LEDs indicate position of the jig with respect to a selected bevel angle, and also what pre-programmed bevel angle is selected. The reference angle of the jig is programmed into the jig by placing the jig on the grinding tool and pressing a pushbutton switch.
