Introduction

GB/T 19903.10 describes the general process data and its schema for CNC machine tools. The theme of the pattern (called ma-

Chinging_schema) is a definition of the type of data typically associated with different processes (eg, milling, turning, EDM). This mode

Includes artifact definitions, feature catalogs (these features may be referenced by several crafts), generic executables, and operational definition bases. Not in mode

Contains geometry items and expressions referenced from ISO 10303 generic resources, and does not include process-specific definitions defined in separate parts of ISO /IEC 15408

definition.

GB/T 19903.10 is not an independent standard and requires at least one additional process-specific part (eg, GB/T 19903.11, for milling)

Cooperate with it. This part of GB/T 19903 describes the spark-forming process (sink-EDM) and defines the EDM.

Art-specific data types.

This part of GB/T 19903 mainly gives the definition and description of the data entity, which is required by the EDM controller.

The entity provides control data information.

The EXPRESS form of these data entities is given again in Appendix A, but there is no information to explain the text.

Appendix B provides another perspective on these data entities, showing graphical representations of different elements in different graphs. These graphic letters

Rich information. The detailed description of the entities of these graphics is given in the corresponding text definition.

In addition, the mode uses processing features similar to ISO 10303.224. Process data description EX- defined in ISO 10303.11

PRESS language. The data encoding uses ISO 10303.21.

1 Scope

This part of GB/T 19903 details the process-specific data elements required for process data for EDM. versus

Together with the general process data described in GB/T 19903.10, this section describes the computer digital controller used in EDM and

An interface between a programming system (eg, a CAM system or a shop floor programming system). This part can be used for the operation of EDM machines.

The scope of this section does not include machine tools for other processes (eg turning, grinding). Other machine tools in other processes in GB/T 19903

3 Terms and definitions

The following terms and definitions defined by ISO 14649-10 apply to this document.

3.1

Roughing roughing

Used to achieve processing operations for etching materials.

Note 1. The purpose of roughing is to remove a large amount of material in a short time, then the quality of the surface is usually not very important.

Note 2. The roughing operation usually follows the finishing operation, see Finishing (3.2).

3.2

Finishing finishing

Machining operations used to achieve the required tolerances.

Note. The finishing operation is usually roughing (3.1), followed by surface finishing (3.3).

3.3

Surface finishing

A processing operation used to achieve the required surface quality.

Note. The finishing (3.2) operation is usually performed before the surface finishing operation.
