Title:
DESIGN METHOD FOR GEAR MACHINING TOOL AND DESIGN ASSISTANCE DEVICE FOR GEAR MACHINING TOOL
Document Type and Number:
WIPO Patent Application WO/2024/057428
Kind Code:
A1
Abstract:
This design method for a gear machining tool (T) comprises: a step (S1) for acquiring gear specifications, tool specifications, and a tooth-profile-direction target modification amount, and performing temporary design of a tool edge shape of the gear machining tool on the basis the gear specifications, the tool specifications, and the tooth- profile-direction target modification amount; a step (S2) for acquiring a tooth-trace-direction target modification amount and determining a correction amount of a machining control element on the basis of the tooth-trace-direction target modification amount; a step (S33) for calculating a first tooth surface shape of the gear on the basis of the correction amount of the machining control element and the temporarily designed tool edge shape; a step (S35) for comparing the first tooth surface shape and a target tooth surface shape and calculating a first subject error in the tooth profile direction on the first tooth surface shape; and a step (S38) for performing main design of the tool edge shape on the basis of the tooth-profile-direction target modification amount and a first subject error modification amount for reducing the first subject error.
