Problems solved by technology
[0004] However, in the actual production in the industry at present, the cost of new equipment is high, and the replacement cycle of new and old equipment is long. Old CNC equipment without automatic tool magazines are still in use in large quantities, and operators still need to manually complete a large number of tool replacements.
In a large number of manual tool replacements, operational errors cannot be completely avoided, which has brought huge economic losses to the entire CNC machining industry
[0005] At present, the prevention of tool use errors in the CNC machining industry is mainly through manual repeated checks, which is low in efficiency and high in risk, and lacks simple, effective, and low-cost error prevention technologies.

Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
[0015] Taking the CNC machining of part 2 of a certain type of aircraft wing as an example, 8 CNC programs need to be run, and the process flow is shown in figure 1 , During the machining process, 4 tool changes are required.
[0016] Such as figure 2 , image 3 As shown, a prompt area 5 is set on the edge of the processing area on the CNC machine bed 1, and its machine coordinate system 4 is determined; a tool prompt nameplate 6 is set in the prompt area 5, and the tool number 7 and the positioning point are generally marked on the tool prompt nameplate 6. 8. Tool name 9, tool specification 10 and pre-store the tool replacement prompt subroutine in the workpiece processing program:
[0017] The subroutines involved take the tool to be replaced with T2 (φ32×26×130×R3.2) at ...

The invention discloses a numerical control machining tool changing mistaken operation preventing method. A prompting area is arranged on the machine tool face of a numerical control machine tool, anda tool prompting nameplate is arranged in the prompting area; in the numerical control machining process, when a tool changing requirement occurs, in the workpiece machining program, a tool replacingprompting sub-program controlling the action of a main shaft is called, so that the equipment main shaft moves to the prompting area and points to a positioning point, corresponding to the tool prompting nameplate, of a tool needing to be replaced, and prompting for an operator is formed.
Description
technical field [0001] The invention relates to the technical field of numerical control machining, in particular to the technology for preventing operation errors in numerical control machining. Background technique [0002] CNC machining is the use of digital control systems such as SIEMENS, FANUC, etc., and the tool is driven by the spindle of the equipment to complete the product processing. The accuracy and precision of the machining are highly dependent on the accuracy of the CNC equipment itself and the precision of the machining tool. [0003] With the development of new CNC equipment, its processing efficiency and precision have reached a very high level. At the same time, the new CNC equipment is generally equipped with an automatic tool magazine, which realizes the comprehensive automation of tool switching and testing. [0004] However, in the actual production in the industry at present, the cost of new equipment is high, and the replacement cycle of new and ol...
