Provided is a simulation device for simulating machining of a machine tool, the simulation device being configured to calculate a designable range of a voxel size on the basis of workpiece shape data, present the designable range of the voxel size to a user, receive designation of the voxel size, and create an image, in which machining of the machine tool is simulated, on the basis of the designated voxel size.

A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine (CMM), including a user interface that comprises a workpiece inspection program simulation portion configurable to display a 3-D view of a workpiece; an editing user interface portion comprising an editable plan representation of a current workpiece feature inspection plan for the workpiece; and an editable alignment program plan representation for the workpiece. The system is configured with the editable alignment program plan representation being automatically responsive to editing operations, regardless of whether the editing operations are performed in the 3-D view or the editable plan representation. The editing operations include deleting or adding at least one workpiece feature to or from the editable alignment program plan representation.

A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer aided design (CAD) file processing portion, an inspection motion path generation portion and a user interface. The user interface includes a workpiece inspection program simulation portion and auxiliary collision avoidance volume creation elements. The workpiece inspection program simulation portion displays a 3D view and the auxiliary collision avoidance volume creation elements are operable to create or define auxiliary collision avoidance volumes that are displayed in the 3D view. In various implementations, rather than requiring a user to model a physical object (e.g., as part of a workpiece or CMM) in a CAD file, the user may instead create and position an auxiliary collision avoidance volume at a location where the physical object is expected to be, so as to prevent collisions that could occur with the physical object.

This dimension estimation device comprises: a calculation unit for calculating, on the basis of a machining program, at least either one of a maximum value and a minimum value of a coordinate value indicating a position included in a cutting path; and an estimation unit for estimating the dimensions of a workpiece prior to machining, on the basis of the at least either one of the maximum value and the minimum value calculated by the calculation unit.

A machined surface estimation device includes: an acquisition unit acquiring tool position data indicating the position of a tool, tool shape data indicating the shape of the tool, and workpiece shape data indicating the shape of a workpiece; a machining simulation unit executing a machining simulation for drawing the workpiece after machining on the basis of the tool position data, the tool shape data, and the acquired workpiece shape data; a machining information calculation unit calculating at least one type of machining information pertaining to the quality of the machined surface on the basis of the tool position data; a selection unit selecting one type of machining information from among the calculated at least one type of machining information; and a display unit displaying, in combination with the workpiece after machining, the selected one type of machining information.
