Introduction to Automation of Production Processes
Automation of production processes involves integrating various systems and technologies to achieve more efficient and productive manufacturing. This requires an understanding of both historical and modern trends in industrial automation.
Industrial automation encompasses a wide range of technologies and processes that enable the automation of manufacturing activities. From simple assembly lines to advanced SCADA systems and PLC programming, industrial automation has significantly evolved over the past decades, contributing to the emergence of the Industry 4.0 concept.
What Can Be Automated?
Automation of production processes is feasible virtually everywhere, and theoretically, everything can be automated, but it is not always cost-effective. While technological possibilities are vast today, the decision to automate a particular process must consider both potential benefits and costs.
Our table presents various production processes that can be automated. Assembly operations may include assembling simple components, welding, soldering, or automatic part feeding. In the field of quality control, automation can involve visual surface inspection, dimensional measurements, label checking, and functional product testing.
Transport and logistics also offer many automation opportunities, such as internal transport using conveyor belts, automatic packaging, labeling, sorting, and warehouse management. Mechanical processing can include cutting and forming sheets, welding, grinding, polishing, and more complex operations like milling and turning.
In chemical processes, automation can be applied to painting, coating, mixing, and dosing chemicals. Material handling can be automated through loading and unloading processes, palletizing, depalletizing, and automatic material dosing and transfer between workstations.
Although technology allows for the automation of almost every aspect of production, it is crucial to assess the profitability of such investments. Automation brings benefits in the form of increased efficiency, cost reduction, and quality improvement; however, implementation, maintenance costs, and potential technological complications must be thoroughly analyzed. Consequently, each automation decision should be preceded by a comprehensive feasibility and cost-benefit analysis.

8. Building and Testing Prototypes
After completing the design phase, prototypes are built and tested. This process is crucial as it allows for verifying theoretical assumptions in practice and early detection of potential problems. During this stage, a safety audit is conducted, as well as tests such as FAT (Factory Acceptance Test) and SAT (Site Acceptance Test).
Safety Audit
The safety audit is the first step in testing prototypes. Its goal is to ensure that all machine components and operational processes meet safety requirements and industry standards. This audit allows for identifying and eliminating potential hazards before conducting more advanced functional tests.
FAT (Factory Acceptance Test)
Factory Acceptance Test is conducted at the manufacturer’s facility and aims to verify whether the prototype meets all technical specifications and design assumptions. The FAT test includes several key stages:
- Documentation review: Before starting the tests, the project team thoroughly reviews all technical documentation to ensure that all components have been installed according to the design.
- Functional tests: Conducting functional tests to check whether the prototype operates according to requirements. These tests may include simulating normal working conditions as well as load tests.
- Safety tests: Checking whether all safety systems operate correctly, including emergency systems, locks, and guards.
- Reporting results: All test results are documented and compared with design assumptions. Any deviations are analyzed, and if necessary, the prototype is modified.
SAT (Site Acceptance Test)
After completing FAT tests, the prototype is transported to the target location, where a Site Acceptance Test is conducted. The SAT test aims to verify whether the system operates correctly in real production conditions. It includes:
- On-site installation: A team of engineers installs the prototype on-site, integrating it with the existing production infrastructure.
- Functional tests: Similar to FAT, functional tests are conducted, but this time in a real working environment. This includes checking all machine functions in the context of the entire production process.
