ASYMMETRICAL CORNER JOINT AND TOOLS FOR MAKING SAME

An asymmetrical corner joint in a material having a planar surface， in which one side of the joint is shaped to be a slanted plane and the other side of the joint is shaped to be a beveled plane and a shoulder plane， such that when the joint is formed the slanted plane and beveled plane abut and the shoulder plane abuts a portion of the planar surface adjacent the slanted plane. A tool set for use with a router for shaping the two sides of the asymmetrical corner joint in one pass， the tool set including a bit with an angle cutting portion and a shoulder cutting portion， and a canting base for use with the router for tilting the angle of rotation of the bit such that the angle cutting portion cuts both sides of the cut and the shoulder cutting portion only cuts one side.

一种加工于具有平面的基材上的非对称角接头（asymmetrical corner joint）：该接头的一侧被加工为倾斜平面（slanted plane），另一侧则被加工为倒角平面（beveled plane）与肩平面（shoulder plane）。当该接头成型后，倾斜平面与倒角平面相互贴合，且肩平面与紧邻倾斜平面的基材平面部分相抵接。本配套电木铣（router）使用的刀具组（tool set），可通过单次走刀完成该非对称角接头两侧的成型加工。该刀具组包含带有倒角切削部（angle cutting portion）与肩面切削部（shoulder cutting portion）的铣刀（router bit），以及配套电木铣使用的可调倾斜底座（canting base）：该底座可调整铣刀的旋转倾斜角度，使倒角切削部同时切削切口的两侧，而肩面切削部仅切削切口的单侧。
