1. A tool load display method comprising:
inputting a machining program that specifies a plurality of tools used during machining work and that specifies machining processes which constitute the machining work and each of which is performed by using each of the plurality of tools;
calculating at least one piece of load information corresponding to each of the plurality of tools during each of the machining processes;
assigning the at least one piece of load information to each of the plurality of tools;
selecting selected load information from the at least one piece of load information;
determining a displaying order of the plurality of tools based on the selected load information assigned to each of the plurality of tools;
displaying on a display of a machine tool, the plurality of tools in the displaying order;
displaying, next to each of the plurality of tools, at least one machining process performed by using each of the plurality of tools, at least one of: a cutting depth of each of the plurality of tools relative to a workpiece; a feed rate of the workpiece; a cutting speed of cutting the workpiece; and a rotational speed of a spindle configured to rotate the workpiece or each of the plurality of tools being defined in the at least one machining process; and
displaying, upon selecting a selected machining process from the at least one machining process displayed, the cutting speed and the feed rate corresponding to the selected machining process and the cutting speed and the feed rate corresponding to a different machining process which is different from the selected machining process and in which each of the plurality of tools is used such that the cutting speeds are comparable with each other and the feed rates are comparable with each other.
