Problems solved by technology

[0005] At present, in the existing technology, during the processing, the cylindrical material is placed on the three-jaw chuck for fixing, because the clamping end of the jaws is generally a plane or conical structure, which will cause the clamping end of the jaws to collide with the cylindrical material. The clamping surface in contact with the curved surface of the curved surface is small, which will cause the cylindrical material to fall off due to unstable clamping during the five-axis cutting process of the curved surface. Therefore, the invention provides a curved surface for processing PEEK materials Five-axis cutting equipment and its control system

Abstract

The invention belongs to the technical field of numerical control machining, and particularly relates to curved surface five-axis cutting equipment used for PEEK material machining and a control system of the curved surface five-axis cutting equipment. The control system comprises the steps that S1, a cylindrical PEEK material workpiece needing curved surface cutting is firstly placed on a three-jaw chuck on a rotating table of a numerical control machine tool, and clamping jaws are driven to fix a to-be-machined workpiece by rotating a pushing part in the three-jaw chuck; and S2, a numerical control machining program is loaded into a numerical control system, and machining program statements are decoded and operated by the numerical control system and are converting into an action instruction for driving each moving component. The curved surface five-axis cutting equipment used for PEEK material machining and the control system of the curved surface five-axis cutting equipment are provided so as to solve the problems that when a cylindrical material is placed on the three-jaw chuck to be fixed, due to the fact that the clamping ends of the clamping jaws are generally of plane or conical surface structures, the clamping surfaces, making contact with the arc-shaped surface of the cylindrical material, of the clamping ends of the clamping jaws are small, and the cylindrical material falls off due to unstable clamping of the clamping jaws.

Description

technical field [0001] The invention belongs to the technical field of numerical control processing, in particular to a curved five-axis cutting device for processing PEEK materials and a control system thereof. Background technique [0002] Polyether ether ketone, the English name polyetheretherketone (abbreviated as PEEK), is a linear aromatic polymer compound containing chain segments in the main molecular chain, and its constituent units are oxygen-p-phenylene-oxygen-carbonyl-p-phenylene, It is semi-crystalline, thermoplastic. The peek material is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength. Parts, automatic washing machine wheels, medical equipment parts, etc. [0003] There are also some technical solutions on CNC machining technology in the existing technology. For example, a Chinese patent with application number 2018221006069 discloses a five-axis cuttin...
