Vision Measuring Machines (VMM) are widely applied in high-precision manufacturing fields such as electronics, mold making, machinery, and medical devices. As a non-contact measurement device, VMM plays a crucial role in guaranteeing measurement accuracy and improving inspection efficiency. However, overlooking basic safety protocols during use may not only damage the equipment but also cause errors, production delays, or even jeopardize operator safety.

To ensure long-term stable operation and reliable measurement accuracy, it is essential to pay close attention to safe operation throughout the usage process. This article systematically outlines safety precautions in multiple aspects including power connection checks, electrical safety, working environment, platform operation, and software usage, helping users protect both the equipment performance and personnel safety.

Power-On Checks Before Operation
Before using the VMM, ensure the power connection is correct and meets the device’s technical requirements. The grounding system must be stable and reliable to prevent static interference and leakage risks. The supply voltage should be within the range specified on the device nameplate to avoid system failures caused by voltage anomalies.

Inspect all power cables, signal cables, and control lines for integrity. Connection points should be tight without looseness or exposed wires. Operators must keep hands dry when connecting power or handling the control panel to minimize electrical shock risk.

Preventing Electrical Safety Risks
The VMM contains complex electrical components and precision control systems. Unauthorized personnel must not open electrical cabinets or modify control wiring. All electrical maintenance should be performed only after the device is completely powered off, with clear “Under Maintenance” signage in place.

Regular inspection of the electrical system is necessary to ensure power connectors are secure, terminals are free from oxidation, and components show no signs of overheating. Maintaining electrical stability is fundamental to equipment longevity and safe operation.

Ensuring a Suitable Working Environment
The VMM’s performance is significantly influenced by environmental conditions. The installation area should have moderate temperature and humidity, clean air, and be free from corrosive gases and oil mist. Stable ambient temperature and humidity prevent component moisture, optical lens fogging, and control system failures.

Avoid placing the device under direct sunlight, strong drafts, or near heavy vibration sources, as these factors can cause image drift and measurement errors. The floor should be sturdy, level, and provide adequate support to maintain platform stability over long-term use.

Planning the workspace layout for easy maintenance and smooth loading/unloading is also important to avoid operational safety hazards or ventilation blockages.

Platform Operation and Workpiece Placement Guidelines
The measuring platform is the direct contact surface with the workpiece and is critical for measurement stability. Prior to measurement, the platform surface must be cleaned of dust, debris, or foreign materials to avoid damage to the glass surface or optical system.

Workpieces should be handled gently to prevent impact damage to the platform structure or guide system. Any processing activities such as cutting, filing, or grinding on the platform are strictly prohibited as they can degrade platform accuracy and flatness.

For environments with frequent loading and unloading, consider using fixtures or protective accessories to secure workpieces, preventing displacement and potential collision with optical or lighting components.

Software Operation and System Usage Considerations
VMM relies on sophisticated software algorithms and automated motion control. To prevent mechanical collisions or measurement errors caused by misuse, implement permission controls on the software, restricting program modification and execution rights to trained personnel only.

Before executing measurement programs, verify motion paths, especially in automated modes, to ensure axes movements do not interfere with workpieces or fixtures. Programs must be validated before running.

During operation, avoid sudden power shutdowns or disconnecting communication interfaces, which can cause data loss, system misalignment, mechanical errors, or servo system damage. Regularly back up configuration parameters and measurement programs to prevent data loss and reduce downtime.

Cultivating Standardized Operating Habits
Safety is not just a requirement but a prerequisite for maintaining measurement efficiency and quality consistency. Companies should establish standardized operating procedures covering every phase: powering on, program loading, workpiece placement, measurement execution, shutdown, and routine maintenance.

Operators should be fully trained to understand device structure, software systems, basic troubleshooting, and emergency handling. Maintaining comprehensive operation records ensures traceability and accountability.

A regular maintenance schedule—covering optical cleaning, platform upkeep, lubrication of moving parts, and electrical system inspections—must be implemented, with trained personnel supported by clear technical guidelines.

Safety Is the Foundation of Measurement Accuracy
As a high-precision measurement instrument, the VMM’s stable and efficient operation depends not only on advanced optics and motion control technology but also on rigorous safety management and standardized operation.

By paying close attention to every operational detail and inspection procedure, equipment performance is maximized, service life is extended, failure rates are reduced, and product quality and production efficiency steadily improve.

Safety is both a responsibility and a habit. The professional awareness of every operator combined with enterprise management forms a solid foundation for stable and reliable measurement systems.
