Abstract
A tool magazine of a machine tool holds machining tools of multiple types. The number of stored machining tools of at least one type is more than one. When all the machining tools of the at least one type are unused, a first test-machining step of machining a workpiece using one machining tool of each type is performed. When the machined product is graded as acceptable, a second test-machining step of replacing the machining tool of the at least one type with an unused machining tool in the tool magazine and machining a new workpiece using the one machining tool of each type is performed. The second test-machining step is repeated until all the machining tools are used.
Claims4
A machining method implemented by a machine tool including a tool magazine storing machining tools of a plurality of types, a spindle to which the machining tools are attached, and a tool changer configured to exchange the machining tools between the tool magazine and the spindle, a number of machining tools of at least one type among the machining tools of the plurality of types stored in the tool magazine being more than one, the machining method comprising:
- a first test-machining step of machining a workpiece using one of the machining tools of each of the plurality of types when all the machining tools of the at least one type are unused;
- and
- a second test-machining step of replacing the machining tool of the at least one type with an unused machining tool in the tool magazine and machining a new workpiece using the one of the machining tools of each of the plurality of types, wherein:
- the second test-machining step is repeated until all the machining tools of the at least one type are used;
- each of the machined workpieces obtained in the first test-machining step and each of the machined workpieces obtained in the second test-machining step undergo quality inspection;
- and
- when all the machined workpieces are graded as acceptable products, the machine tool shifts to a full machining step of continuously machining workpieces using one of the used machining tools of each of the plurality of types while the workpieces are changed.
