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 for standardization documents" Drafting is required. This document replaces GB /Z 18462-2001 "Performance specification and standard inspection procedure for metal cutting of laser processing machinery" and Compared with GB /Z 18462-2001, in addition to structural adjustments and editorial changes, the main technical changes are as follows. Increased the scope of application (see Chapter 1); a) The terms and definitions of trailing angle, nodule, complete cutting and interrupted cutting (see 3.1, 3.2, 3.3 and 3.5 of the.2001 edition) have been deleted; b) Added the terms and definitions of dross and verticality (see 3.1 and 3.5); c) Added cutting performance requirements for laser processing machinery (see 4.1 and 4.2); d) Deleted mechanical and process parameters (see Chapter 4 of the.2001 edition); e) The evaluation and classification of cutting performance has been modified and added to the performance requirements for cutting metal parts (see 4.3, 5.1 and 5.2); f) The contents of 5.3, 5.4 and 5.5 have been modified (see 5.2, 5.3, 5.4 and 5.5 of the.2001 edition); g) Added cutting performance test for laser processing machinery (see 5.1); h) Added inspection rules (see Chapter 6). i) Please note that some of the contents of this document may involve patents.
