Definition of a Machine (Equipment Safety Act)

Definition of a Machine 

“A machine is an assembly of interconnected parts or components, at least one of which is movable, and which is equipped with or intended to be equipped with a drive system other than directly applied human or animal power, and which is joined together for a specific function.”

Definition of Equipment:

“Equipment is a pressure, gas or electrical device, a machine or a technical system composed of such devices, or any other object in which the contained energy or fluid, or the process taking place within it, by its nature creates a hazard to human life or health, property or the environment, even when handled with the level of care expected from a competent professional.”

Our Approach to Equipment Design 

 The above definitions form the legal basis for machine design. Mechanical engineering is not merely the creation of drawings but a process that ensures the intended and safe operation of the designed equipment or machine. This process always begins with defining the problem and the task. Even with an experienced client who already has an initial design brief, it must be thoroughly discussed and structured in writing. The design brief records the project objective, existing situation, desired outcome, required design stages and decision points, the normative documents to be followed, and the tasks and services included or excluded from the project. According to the client’s needs and capabilities, we can provide projects and machine construction at various levels of completeness.

Scope of Nõmm Insenerid OÜ Services in Equipment Design

 Our engineers work with: designing mechanisms and drive systems structural strength calculations (analytical methods + FEM) preparing and evaluating machine risk assessments throughout the design cycle assessing dynamic loads selecting materials and determining manufacturing technologies optimising parts and assemblies for reliability and cost‑efficiency automation design based on prepared functional diagrams selecting sensors and actuators defining machine safety measures and their levels based on risk assessment

Prototype Construction and Testing 

 Understanding a more complex process requires testing the product or material before developing the final structural solution. The company has a well‑equipped workshop for prototyping and building medium‑sized equipment. A key part of our full service is prototype construction, which enables us to: verify mechanism operation assess loads and wear points test automation identify structural weaknesses make improvements before mass production We can build prototypes up to 4 × 2.5 m in size, and larger production lines when required. Development does not end with drawings. Even when another company manufactures the equipment or machine, we always provide support during construction and testing. All our drawings include a note encouraging the manufacturer to call or write: “If in doubt, ask!”

Services Provided by Our Collaboration Network

A modern production machine is not only mechanics – it is the precise integration of automation, control logic and safety functions. Our partners cover: designing PLC and industrial control systems creating HMI and SCADA solutions implementing safety functions (SIL/PL) integrating servo drives and frequency converters preparing automation documentation Automation solutions are based on industrial standards (e.g., ISO 13849, IEC 62061), ensuring equipment safety and reliability.

Success Stories in Machine Design

 Thanks to long‑term experience in designing equipment for the wood, paper and metal industries, we can provide solutions that operate in demanding conditions and meet industrial standards. See the machines and equipment we have designed.

Project Management and Documentation

 Project management is critical in the development of complex equipment. We provide: schedule preparation risk assessment and safety documentation CE‑marking preparation technical file compilation supplier coordination testing and commissioning management Project management ensures that development proceeds according to plan and all parties work towards a common goal.
