Machine tool, tool load display method for machine tool, and program for machine tool

The invention provides a machine tool, a tool load display method for the machine tool, and a program for the machine tool. A tool load display method for a machine tool displays a plurality of tools specified by a machining program and at least one machining process for each of the plurality of tools, and when a selected machining process is selected from the displayed at least one machining process, displays load information and a value of a cutting parameter during the selected machining process. At least one parameter value among the displayed cutting parameters is changed to a correction value, load information is recalculated based on the correction value, and the recalculated load information is displayed. 本发明提供机床、机床的刀具负荷显示方法和用于机床的程序。机床的刀具负荷显示方法显示由加工程序规定的多个刀具以及多个刀具的各刀具的至少一个加工过程，当从显示的至少一个加工过程中选择了被选择加工过程时，显示被选择加工过程中的负荷信息和切削参数的值，并将显示的所述切削参数中的至少一个参数的值变更为修正值，基于修正值再次计算负荷信息，并显示再次计算出的负荷信息。
