Abstract
To make it possible to evaluate quantitatively whether there is a problem on a machining surface. A simulator includes a memory unit that stores machining position data to be used when a machine tool machines a machining-target object, a machining surface simulation unit that uses the machining position data that is stored to perform a simulation of a machining surface, a surface texture calculation unit that calculates a surface texture of the machining surface that is simulated through the simulation of the machining surface, and a machining surface evaluation unit that evaluates the surface texture on the basis of an evaluation condition.
Claims6
A matching simulator apparatus for quantitatively visualizing a machining surface comprising:
- a user interface configured to receive a simulation start request for a selected area of a machining surface of a machining-target object;
- a non-transitory memory configured to store one or more programs and machining position data to be used when a machine tool machines the machining-target object;
- and
- a hardware controller configured to execute the one or more programs to:
- read the machining position data that is stored to perform a machining simulation of the selected area of the machining surface;
- divide the selected area of the machining surface that is simulated into a plurality of portions;
- calculate a surface texture parameter value for each of the portions of the selected area of the machining surface;
- evaluate the surface texture parameter value of each of the portions of the selected area of the machining surface on a basis of an evaluation condition, the evaluation condition being whether the surface texture parameter value of each of the portions of the selected area of the machining surface exceeds a threshold value;
- determine a display method for displaying on a screen a result of the evaluation of the surface texture parameter value of each of the portions of the selected area of the machining surface;
- and
- display on the screen of the user interface the result of the evaluation of the surface texture parameter value of each of the portions of the selected area of the machining surface on the basis of the determined display method,
- wherein the determined display method for portions of the selected area of the machining surface with surface texture parameter value that exceeds the threshold value is different from portions of the selected area of the machining surface with surface texture parameter value that do not exceed the threshold value.
