MACHINING TIME PREDICTION DEVICE, CUTTING SYSTEM, AND MACHINING TIME PREDICTION METHOD

Title:

MACHINING TIME PREDICTION DEVICE, CUTTING SYSTEM, AND MACHINING TIME PREDICTION METHOD

Document Type and Number:

WIPO Patent Application WO/2017/159772

Kind Code:

A1

Abstract:

The present invention predicts with high accuracy the remaining machining time needed for cutting. A control device (74) for a machining time prediction device (70) is provided with: a storage unit (82) in which a machining program having a plurality of steps is stored; a simulation unit (83) that conducts a simulation of a cutting machine cutting a workpiece according to the machining program, and creates a control pattern in which control information for a spindle and a holding unit is recorded; a machining time calculation unit (88) that creates, on the basis of the control pattern, a machining time table in which the remaining machining time for each step of the machining program is recorded; a machining time acquisition unit (89) that acquires a step of the machining program of the cutting currently being performed by the cutting machine, and acquires, from the machining time table, the remaining machining time for the acquired step of the machining program; and a display unit (90) that displays, on a display screen (72), the remaining machining time acquired by the machining time acquisition unit (89).
