Modified angle-plate jig a variation in the angle-plate jig is called as angular jig, which is used for machining angles other than 90 degrees. Both of these examples have clearance problems with the cutting tool.
As the drill exits the product being drilled, it has little or no room for the drill point to clear the product completely, produce a round hole all the way through the part wall, and avoid drilling the part locator.
This is most noticeable in Figure, where an angled hole requires additional clearance to the relieved portion of the part locator.
Additional clearance here would allow the drill to complete the hole and avoid drilling the relieved portion of the locator.
The part locator will most likely be hardened and the drill will be lost as a result of any attempted drilling.
Additional clearance on the relieved diameter of the part locator may be possible.
A larger clearance hole in the locator could also be added if the relieved diameter cannot be reduced. The additional design consideration added to the locator would include the feature to provide the correct orientation of this clearance hole or machined relief to line up with the bushing location.
