Abstract
An edge break apparatus including a frame having a first workpiece interface surface, a second workpiece interface surface arranged relative to the first workpiece interface surface so as to form a predetermined angle between the first workpiece surface and the second workpiece surface, and a first aperture extending through the frame so as to intersect the predetermined angle, and an edge break member extending through and interfaced with the first aperture so as to adjustably define a cutting depth of the edge break member relative to an apex of the predetermined angle.
Claims20
An edge break apparatus comprising:
- a frame having
- a first workpiece interface surface,
- a second workpiece interface surface arranged relative to the first workpiece interface surface so as to form a predetermined angle between the first workpiece interface surface and the second workpiece interface surface,
- a first aperture extending through the frame so as to intersect the predetermined angle, and
- a plurality of frame protrusions;
- and
- an edge break member having
- a housing configured to extend through and engage the first aperture, the housing includes threads forming at least part of an exterior surface of the housing, and
- an engagement member having a plurality of engagement member protrusions configured to mate with the plurality of frame protrusions so as to adjustably define, in a plurality of predefined rotational increments of the engagement member, a cutting depth of the edge break member relative to an apex of the predetermined angle, wherein the edge break member is configured so as to be rotationally fixed relative to the frame in each of the plurality of predefined rotational increments.
An edge break apparatus comprising:
- a frame having:
- a first aperture, and
- edge surfaces, each edge surface being configured to engage a respective workpiece surface adjacent a corner of a workpiece;
- and
- an edge break member extending through the first aperture, the edge break member being configured to cut the corner of the workpiece to provide a predetermined workpiece edge contour;
- where the edge break member is coupled to the frame so as to be incrementally movable relative to the edge surfaces for adjustably increasing or decreasing a size of the predetermined workpiece edge contour, the edge break member being incrementally movable so as to be rotationally fixed relative to the frame in each of a plurality of predefined rotational increments;
- and
- wherein the frame includes a plurality of frame protrusions and the edge break member includes a plurality of engagement member protrusions configured to mate with the plurality of frame protrusions to define the plurality of predefined rotational increments of the edge break member relative to the frame.
