Abstract

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.

First claim

1 . A dimension estimation device comprising:
a calculation unit configured to calculate at least one of a maximum value and a minimum value of coordinate values indicating positions included in a cutting path based on a machining program; and an estimation unit configured to estimate a dimension of a workpiece before machining based on at least one of the maximum value and the minimum value calculated by the calculation unit.

2 . The dimension estimation device according to claim 1 , wherein the calculation unit draws the cutting path in a virtual plane or a virtual space, and calculates at least one of the maximum value and the minimum value of the coordinate values based on the cutting path drawn in the virtual plane or the virtual space.

3 . The dimension estimation device according to claim 1 or 2 , wherein the coordinate values include a first coordinate value indicating a position in a first axial direction and a second coordinate value indicating a position in a second axial direction.

4 . The dimension estimation device according to any one of claims 1 to 3 , further comprising a display unit configured to display the dimension of the workpiece before machining estimated by the estimation unit.

5 . The dimension estimation device according to any one of claims 1 to 4 , further comprising a reception unit configured to receive shape information indicating a shape of the workpiece.

6 . The dimension estimation device according to any one of claims 1 to 5 , further comprising a reflection unit configured to reflect the dimension of the workpiece before machining estimated by the estimation unit on the machining program.

7 . The dimension estimation device according to any one of claims 1 to 6 , further comprising a machining simulation unit configured to execute machining simulation based on the dimension of the workpiece before machining estimated by the estimation unit.

8 . The dimension estimation device according to any one of claims 1 to 7 , wherein the estimation unit further estimates the dimension of the workpiece before machining based on a cutting depth.

9 . A computer-readable storage medium storing a command causing a computer to execute:
calculating at least one of a maximum value and a minimum value of coordinate values indicating positions included in a cutting path based on a machining program; and estimating a dimension of a workpiece before machining based on at least one of the maximum value and the minimum value which is calculated.
