Machine tool, tool load displaying method for machine tool, and non-transitory computer-readable storage medium

A machine tool comprising:

• a display configured
• to display tools specified by a machining program;
• and
• to selectively display at least one of machining processes which are specified by the machining program and each of which is performed by using each of the tools;
• an interface via which a selected machining process is selected among the at least one of machining processes that is displayed and via which a selected tool is selected among the tools;
• and
• a processor configured to calculate load information in the selected machining process,
• wherein upon selection of the selected machining process, the display is configured to display the load information and values of machining parameters in the selected machining process,
• wherein upon selection of the selected tool among the tools, the display is configured to display a first selection window showing at least one replacement tool replaceable with the selected tool so as to select a selected replacement tool,
• wherein upon selection of the selected replacement tool among the at least one replacement tool, the display is configured to display a second selection window showing at least one machining process performed by using the selected tool so as to select at least one selected replacement-tool machining process to be performed by using the selected replacement tool, and
• wherein upon selection of the at least one selected replacement-tool machining process, the processor is configured to calculate, in each of the at least one selected replacement-tool machining process, values of the machining parameters of the selected replacement tool so that a machined shape to be formed by the selected replacement tool is substantially identical to a machined shape to be formed by the selected tool.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute processing comprising:

• displaying tools specified by a machining program;
• selectively displaying at least one of machining processes which are specified by the machining program and each of which is performed by using each of the tools;
• displaying load information and values of machining parameters in a selected machining process which is selected among the at least one of machining processes that is displayed;
• obtaining a selected tool selected among the tools;
• displaying a first selection window showing at least one replacement tool replaceable with the selected tool so as to select a selected replacement tool among the at least one replacement tool;
• displaying a second selection window showing at least one machining process performed by using the selected tool so as to select among the at least one machining process, at least one selected replacement-tool machining process to be performed by using the selected replacement tool;
• and
• calculating, in each of the at least one selected replacement-tool machining process, values of the machining parameters of the selected replacement tool so that a machined shape to be formed by the selected replacement tool is substantially identical to a machined shape to be formed by the selected tool.
