The quality, performance and cost of woodworking machinery are determined by the work at the design stage. In the design of mechanical products, we must implement the principle of safety firstly and put safety design in an important position of the machine. Safety design can effectively save energy and reduce costs. The premise of making the good and cheap product is the safety and reliability of the product. Therefore, the safety of woodworking machinery products must be highly valued by designers, because it is not only an economic issue, but also a social issue of great concern to the whole society. Safety design of woodworking machinery needs to consider four aspects: part safety, whole machine safety, work safety and environmental safety.

1. Safety of woodworking machinery parts

Machine parts do not break, excessive deformation, excessive wear, excessive corrosion and stability. In order to ensure the safety of the parts, it is necessary to design them with sufficient strength, stiffness, wear resistance and corrosion resistance, and stability under pressure. These are the places where designers should attach importance to and not allow problems to occur.

2. Safety of woodworking machinery

The whole technical system achieves the total functions under the specified conditions. The realization of the total functions of woodworking machinery is mainly determined by the design of functional principles, and is related to the safety of parts and other factors. Because of the damage or failure of parts, the total function of the real technical system is difficult to achieve, affecting the safety of the whole machine.

3. Woodworking machinery working safety

Work safety refers to the protection of operators and the protection of personal safety and physical and mental health. In order to truly achieve work safety, we must apply the theory of human efficacy to the design of mechanical products, make the relationship between people and machines coordinate reasonably, and embody the people-oriented design concept.

4. Environmental safety of woodworking machinery

The surrounding environment of the whole system and people do not cause harm and pollution, but also to ensure the adaptability of machinery to the environment. In the production design of woodworking machinery, in order to reduce costs and improve economic benefits, it is easy to ignore environmental safety, which may cause the pollution of mechanical work to the atmosphere, and bring harm to human health and even life. The four aspects of safety design of woodworking machinery products are a whole. They are interrelated and influence each other. Safety design reflects the quality of product design to a great extent, so designers must pay enough attention to it.
