SIST EN ISO 15616-4:2021 PDF

Overview

SIST EN ISO 15616-4:2021 specifies the minimum requirements and practical test methods for acceptance testing of CO2-laser beam machines used for high quality welding and cutting with 2-D moving optics. The standard applies to machines where the workpiece remains fixed on the platen and the optics move in two dimensions, ensuring the machine's performance meets rigorous industrial demands. This part of the ISO 15616 series provides a structured approach to verify machine capability, focusing on accuracy and consistency during precision fabrication operations.

ISO 15616-4:2008 is not intended for CO2-laser beam systems with articulated robots, or those featuring integrated work stations (e.g., welding positioners or fixed board cutters). It also does not address hazard protection devices related to particle discharge.

Key Topics

Acceptance Test Conditions

• Requirements for basic installation, including vibration and temperature control
• Compliance of power supply, gas supply, and cooling systems with manufacturer specifications
• Provision of essential operational and safety instructions

Accuracy Verification Acceptance tests cover:

• Trajectory accuracy (tracking the programmed path)
• Straightness of motion along X and Y axes
• Squareness between X and Y movements
• Positioning accuracy in both axes
• Machining speed consistency

Test Preparation and Execution

• Verification of machine parts and measuring instruments
• Calibration requirements for measurement tools
• Standardized trajectory and straightness tests using marking instruments or controlled laser output

Test Reporting

• Detailed reporting format including model and serial numbers, test dates, test locations, responsible personnel, and calibration records

Applications

Practical Value in Manufacturing

• Quality Assurance: Ensures 2-D CO2-laser machines consistently produce precise welds and cuts, critical in industries such as automotive, aerospace, and fabrication.
• Procurement and Commissioning: Assists end-users and manufacturers to objectively verify equipment capabilities before acceptance or commissioning.
• Machine Calibration and Maintenance: Provides clear performance benchmarks for ongoing calibration and periodic testing, essential for maintaining machine accuracy and reliability.
• Contract Compliance: Offers a transparent, standardized assessment protocol when fulfilling contractual or regulatory requirements for precision metalworking machinery.
