Scope: This part of GB/T 14896 defines the terms and definitions of the name, parameters, main components and processing methods of laser processing machine tools. This part applies to all types of laser processing machine tools and their auxiliary equipment and accessories.

Introduction

1. Standard Overview

GB/T 14896.9—2018 "Special Processing Machine Tool Terminology Part 9: Laser Processing Machine Tool" is my country's first terminology standard specifically for laser processing machine tools, aiming to unify and standardize professional terms in the industry.

2. Background of Standard Formulation

With the widespread application of laser technology in the manufacturing field, the demand for standardization in the industry is becoming increasingly urgent. This standard was proposed by the China Machinery Industry Federation and is managed by the National Special Processing Machine Tool Standardization Technical Committee, which embodies the wisdom of many universities and enterprises.

3. Comparison of standard frameworks

Standard part	GB/T 14896.9—2018	References
Scope definition	Define the name, parameters, main components and processing method terms of laser processing machine tools.	GB/T 14896.1—2009, GB/T 15313—2008
Machine tool name	Including laser cutting, welding, cladding and other processing methods.	GB/T 14896.7—2015
Parameter Definition	Covering key indicators such as beam quality, power density, wavelength, etc.	-

4. Interpretation of the main content

4.1 Classification of laser processing machine tools

Laser processing machine tools are mainly divided into four categories: cutting, welding, cladding and surface treatment. For example: Fiber laser cutting machine tools use fiber laser as the energy source and are suitable for high-precision cutting; Nd:YAG solid laser cutting machine tools are suitable for deep cutting of metal materials.

4.2 Analysis of key terms

Beam quality factor: An important indicator to measure the focusing ability of the laser beam, which directly affects the processing accuracy.
Pulse width: Defined as the interval between 50% peak power points, the pulse width of ultrafast laser is less than $10\mathrm{ps}$.

4.3 Comparison of processing methods

The following is a comparative analysis of several typical processing methods:

Processing method	Definition	Application scenario
Laser melting cutting	The use of high-speed airflow to blow away the molten material.	Metal material cutting
Laser vaporization cutting	Directly vaporize the material to form an incision.	Non-metal material processing
Laser stress cutting	Induce crack propagation through thermal stress.	Brittle material cutting

5. Implementation suggestions

To ensure the effective implementation of the standard, it is recommended that:

Enterprises should organize technical personnel to learn and master the content of the standard.
Reference to standard terms in equipment procurement and R&D to avoid ambiguity.
Promote the wide application and dissemination of the standard in the industry.
