Embodiment Construction

[0085] Such as figure 1 As shown, the present invention includes a data interface, a parameter setting module, a data processing module, an analog feedback module, an analysis and evaluation module, a display module and a test code library. The data interface can be the field bus interface of the numerical control system, or the analog quantity or pulse quantity interface of the numerical control system.

[0086] The analog feedback module, when establishing a mathematical simulation model, applies mathematical modeling and simulation tools, and calls the module library to perform PID control on the position loop, speed loop, and current loop of the servo system in the CNC system, and establishes it through multi-rate discrete modeling Servo system simulation model.

[0087] figure 2 Shown is a schematic diagram of the simulation model of the single-axis feed system of the machine tool established by the simulation feedback module in the present invention. Open source or c...

Abstract

The invention discloses a detection analysis device for technical indexes of a numerical control device, belongs to a test device for the numerical control device, and solves the problems that the conventional detection analysis devices for the technical indexes of the numerical control device are not universal for various numerical control devices and the detected and analyzed technical indexes are not comprehensive. The detection analysis device comprises a data interface, a parameter setting module, a data processing module, an analog feedback module, an analysis evaluation module, a display module and a test code library. The data processing module computes the indication data received by the data interface, and the test result is output to the analysis evaluation module and the display module. The parameter setting module sets parameters of the analog feedback module. The test code library provides standard test G codes for each item to be tested. The detection analysis device for the technical indexes of the numerical control device simulates characteristics of actual servo drive, motor and machine tool by using the analog feedback module, computes corresponding feedback data, removes the influence of uncertainty of an actual electromechanical system and inconsistent processing performance of the machine tool, and can accurately and objectively analyze and evaluate each important technical index of the numerical control device.

Description

technical field [0001] The invention belongs to a testing device for a numerical control device, in particular to a detection and analysis device for technical indicators of a numerical control device. Background technique [0002] At present, for the comprehensive evaluation of the technical indicators of the numerical control device and the functions of each module, it is generally used to directly process the comprehensive test piece containing various geometric features on the numerical control machine tool, and use the geometric dimensions of the final processed test piece to judge the performance of the numerical control device. However, there are many factors that affect the geometric accuracy of the final test piece. In addition to the technical indicators of the numerical control device itself, there are also: position servo system error, machine tool mechanical accuracy, and the error of measuring tools and instruments used for testing. Therefore, the technical ind...
