8.Electro-Mechanical Processing Machine Tools", and is consistent with... Compared with GB/T 14896.8-2009, apart from structural adjustments and editorial changes, the main technical changes are as follows:

a) Change the processing method from "electro-melting explosion machining" to "electric arc machining" (see 3.1,

6.1 in the.2009 edition);

1 Scope

GB/T 14896.8-2025 is the Chinese national standard on non-traditional machines - terminology - part 8: electrical arc machines, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2026. Classification: ICS 25.080.99, CCS J59. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document defines the processing methods, names, parameters and processes of electric arc machining tools, as well as the terminology for their main components. This document applies to all types of arc machining machines (including equipment).

3 Processing Method

3.1 In a specific medium, an electric arc discharge is generated between the workpiece and the tool electrode, causing the workpiece material to melt, vaporize, and be removed. method. [Source: GB/T 14896.1-2025, 3.7]

3.2 An arc machining method using a forming tool electrode.

3.3 electric arc milling Using rod-shaped or tubular electrodes, the workpiece is shaped point-by-point (surface-by-surface) in a manner similar to the relative motion between the milling cutter and the workpiece during mechanical milling. Arc machining method.

3.4 electric arc turning Arc machining using rod-shaped, tubular, or disc-shaped electrodes, following a relative motion pattern between the cutting tool and the workpiece similar to that in mechanical turning. method.

3.5 electric arc cutting An arc machining method that uses rod-shaped or wire electrodes to cut the workpiece in a manner similar to the movement of the electrode wire in wire electrical discharge machining.

3.6 electric arc drilling An electric arc machining method that uses rod-shaped or tubular electrodes to drill holes in a workpiece in a manner similar to the movement of a drill bit during mechanical drilling.
