The quality, performance and cost of woodworking machinery products are largely determined by the work in the design stage. In the design of mechanical products, we must implement the policy of safety first and put the safety design in the important position of the machine. Effectively save energy and reduce costs through safe design. The premise of good quality and low price is that the product is safe and reliable. Therefore, the safety of woodworking machinery products must be highly valued by designers, because it is not only an economic problem, but also a social problem that the whole society is very concerned about.

The safety design of woodworking machinery needs comprehensive consideration of parts safety, machine safety, work safety and environmental safety.

1. Woodworking machinery parts safety

It is mainly stipulated that the external load and the specified time, the parts do not break, excessive deformation, excessive wear, excessive corrosion and do not lose stability. In order to ensure the safety of parts, the design must make it have enough strength, enough stiffness, necessary wear resistance and corrosion resistance and compression stability. These are the need for designers to pay great attention to and not allow problems.

2. Safety of woodworking machinery

The whole technical system realizes the total function under the specified conditions. The total function of woodworking machinery products is mainly determined by the design principle of the function, but also closely related to the safety of parts and other factors. Often because of the destruction or failure of parts, but the total function of the technical system is difficult to achieve, affecting the safety of the whole machine.

3. Woodworking machinery work safety

Work safety refers to the protection of operators, the protection of personal safety and physical and mental health. In order to truly achieve work safety, we must apply the theory of human ergonomics and only to the design of mechanical products, so that the relationship between people and products is reasonable coordination, reflecting the people-oriented design concept.

4. Woodworking machinery environment safety

The surrounding environment and people of the whole system do not cause harm and pollution, but also ensure the adaptability of the machinery to the environment. In the design of woodworking machinery, in order to reduce costs and improve economic benefits, it is easy to ignore environmental safety, which may cause atmospheric pollution of mechanical work, harm to people's health and even life.

The four aspects of woodworking machinery product safety design are a whole, they are interrelated and influence each other. Safety design reflects the quality of product design to a large extent, so designers must pay enough attention to it.
