Scope
GB/T 40328-2021 is the English-translated version of 工业机械电气设备及系统 数控加工程序编程语言.
GB/T 40328-2021 defines a programming language for machining programs in the numerical control systems of industrial machine electrical equipment.
It extends GB/T 8870.1-2012 and covers macro programs, with the form of macro variables, the program format and IF and WHILE jumps and loops, together with built-in functions for arithmetic, tool information, system parameters, coordinate systems, human-computer interaction, file and channel operations.
It also sets out motion control G code instructions and motion control function blocks such as MC_MOVEABSOLUTE, MC_MOVERELATIVE, MC_HOME and MC_READPARAMETER, with annexes giving macro program examples and a user macro command table.
The aim is that programs can be exchanged between comparable CNC machine tools. It was issued on 20 August 2021 and has applied since 1 March 2022.

Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.
Introduction
This document is an extension of GB/T 8870.1-2012. The CNC system supports the programming format defined in this document and GB/T 8870.1- The programming format defined in 2012 is mixed programming.
Standardize the macro program and G code instruction format in the industrial machinery CNC, which helps to coordinate the system design, calculation and human-computer interaction requirements, from And to promote the unification of programming technology, and make it between the same classification of CNC machine tools such as model, processing technology, function, size and accuracy. The input program is interchangeable.
Determine a simple and uniform format for programming operations of CNC machine tools. For more complex machinery, only the systematic Further extension.
1 Scope
This document specifies the relevant macro program, G code and motion in the programming language of the CNC machining program of the electrical equipment and system of industrial machinery. Function block requirements.
This document applies to the numerical control system of industrial machinery electrical equipment and systems.
2 Normative references
The contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document.
GB/T 8870.1-2012 Automation System and Integrated Machine Tool Numerical Control Program Format and Address Word Definition Part 1: Data format of point position, linear motion and contour control system
3 Terms and definitions
The following terms and definitions defined in GB/T 8870.1-2012 apply to this document.
3.1 Macro-program
A numerical control system (NC) programming language that can perform expression calculations and conditional jumps. A special program written by the user, available as specified As the code name.
3.2 Macro-variable
The variables that temporarily save data provided to the user in the macro program can directly participate in calculations and G code programming.
3.3 Expression
It is composed of numbers, operators, number grouping symbols (parentheses), free variables and constraint variables, etc., in order to obtain numerical and meaningful rankings. A combination of column methods.
3.4 IF conditional jump
A way to judge whether the expression after IF is true in the current situation, if it is true, then the expression is followed by the expression, if it is not true, it is not executed The macro program of the expression followed by THEN.
3.5 WHILE loop
A way to determine whether the expression followed by WHILE is true in the current situation, if it is true, execute DO followed by the expression, and loop until WHILE is followed by a macro program whose expression is not true to jump out of the loop.
