Abstract
A determining tool for use in determining the shape of the tip end of a machining tool that machines a workpiece held on a table while the machining tool moves relatively to the table includes a bottom surface adapted to be held on the table and a flat slanting surface inclined to the bottom surface and oriented across a direction in which the machining tool moves relatively to the table, the flat slanting surface being adapted to be cut through by the tip end of the machining tool.

A determining tool for use in determining a shape of a tip end of a machining tool that machines a workpiece held on a table while the machining tool moves relatively to the table, the determining tool comprising:
- a bottom surface adapted to be held on the table;
- and
- a flat slanting surface inclined to the bottom surface and oriented across a direction in which the machining tool moves relatively to the table, the flat slanting surface being adapted to be cut through by the tip end of the machining tool.
A shape determining method of determining a shape of a tip end of a machining tool that machines a workpiece held on a table while the machining tool moves relatively to the table, the method comprising:
- holding, on the table, a bottom surface of a determining tool that includes the bottom surface and a flat slanting surface inclined to the bottom surface;
- causing the tip end of the machining tool to cut into the determining tool in such a manner as to cut through the slanting surface while the slanting surface is directed across a direction in which the machining tool moves relatively to the table;
- and
- checking a shape of a machining mark left on the slanting surface by the tip end of the machining tool that has cut through the slanting surface, from a side of the determining tool that is opposite to the bottom surface, thereby determining the shape of the tip end of the machining tool.
