Visualizer, machining system, visualization method, and visualization program

A visualizer that visualizes a machining status of a workpiece, the visualizer comprising:

• a data acquirer configured or programmed to acquire data from a machine tool;
• and
• a renderer configured or programmed to render an image showing a shape of the workpiece and display the image on a display;
• wherein
• the data acquirer is configured or programmed to acquire first data that enables identification of a position of a tool during machining, and second data that indicates load currents of a feed axis motor and a spindle motor during machining;
• and
• the renderer is configured or programmed to render the image based on the first data and vary a display mode in the image between a first machined portion and a second machined portion where cutting resistance received by the tool, estimated based on the second data, differs.

A machining system including a machine tool that machines a workpiece, the machining system comprising:

• a machine tool to machine a workpiece;
• and
• a visualizer configured or programmed to visualize a machining status of the workpiece;
• wherein
• the visualizer is configured or programmed to include:
• a data acquirer configured or programmed to acquire data from the machine tool;
• and
• a renderer configured or programmed to render an image showing a shape of the workpiece and display the image on a display;
• wherein
• the data acquirer is configured or programmed to acquire first data that enables identification of a position of a tool during machining, and second data that indicates load currents of a feed axis motor and a spindle motor during machining;
• and
• the renderer is configured or programmed to render the image based on the first data, and vary a display mode in the image between a first machined portion and a second machined portion where cutting resistance received by the tool, estimated based on the second data, differs.

A visualization method for visualizing a machining status of a workpiece, the method comprising:

• acquiring data from a machine tool;
• and
• rendering an image showing a shape of the workpiece and displaying the image on a display;
• wherein
• first data that enables identification of a position of a tool during machining, and second data that indicates load currents of a feed axis motor and a spindle motor during machining are acquired;
• the image based on the first data is rendered;
• and
• a display mode is varied in the image between a first machined portion and a second machined portion where cutting resistance received by the tool, estimated based on the second data, differs.

A non-transitory computer-readable medium including a visualization program executable to cause a computer to function as a visualizer to visualize a machining status of a workpiece, a data acquirer to acquire data from a machine tool, and a renderer to render an image showing a shape of the workpiece and display the image on a display;

• wherein
• the data acquirer acquires first data that enables identification of a position of a tool during machining, and second data that indicates load currents of a feed axis motor and a spindle motor during machining;
• and
• the renderer renders the image based on the first data and varies a display mode in the image between a first machined portion and a second machined portion where cutting resistance received by the tool, estimated based on the second data, differs.
