Embodiment

[0029] On the FANUC CNC machine tool, fix the processed cylindrical mold steel with a fixture, set the relevant program, and select the cutting tool for turning (according to the actual situation of the groove depth, groove width and pitch of each section of the screw rod, Choose a tool with a different number), after programming, use the serial interface to transmit the NC machining program of the screw. After the three-dimensional coordinate parameters, further adjust the fine-tuning equipment and fixtures to ensure one-time processing and molding, which is also an important method to improve the qualified rate of processed products. After everything is ready, start the CNC machine tool equipment and formally process and manufacture the three-variable screw. After the three-stage program runs, the processing of the three-variable screw is completed. The finished product is unloaded from the jig, measured, inspected, and put into the machine. library. In this way, a section ...

Abstract

The invention relates to a turning and cutting control method of a trivariant screw, which comprises the following steps: (1) establishing a corresponding mathematic model; (2) converting the mathematic model to a method that guides a numerical control (NC) machine to conduct machining, developing a human-computer interface of a trivariant screw machining program by using Visual Basic language, and automatically generating the NC code of a numerical control program and simulating manufacturing of the numerical control code; (3) introducing Cut Viewer Turn special software to verify; and (4) actually operating with the numerical control machine. The method has low machining cost, and is simple and easy to use with no need to improve the device and purchase an advanced multi-axis linkage numerical control machine. Trivariant screws can be machined on many of exiting numerical control machines by only introducing a machining control program.

Description

Technical field: [0001] The invention relates to a processing method of a numerical control lathe, in particular to a turning processing control method of a special-shaped screw, that is, a three-variable screw with variable pitch, variable groove depth, and variable groove width. Background technique: [0002] The three-variable screw is used in the waterproof nylon zipper molding machine. It is a screw in injection molding equipment. The screw has the characteristics of variable pitch, variable groove depth, and variable groove width (that is, three-variable screw). It is a high-tech The special-shaped screw, the structure of the screw will directly affect the injection molding results of the zipper molding machine, and affect the quality of waterproof nylon zipper products. [0003] At present, the three-variable screw is a difficult point in the processing of special-shaped screws. For the current domestic processing equipment such as CNC machine tools, it cannot meet th...
