The development of a new part begins with a complete analysis of its functionality, which includes calculations of force loads, strength, vibration resistance and wear resistance of the future product. These parameters, along with the shape and consideration of production technology, determine the choice of material and product design. The entire development process is described in detail in the drawing, which serves as a basis for the creation of a production flow chart. Any metal products to order can be properly executed only in the presence of a full-fledged project. This documentation is a kind of map for machine operators, who develop programs for their control, ensuring accurate compliance with the specified parameters and the quality of the final product.
Metal parts to order: when do I need a drawing?
For the correct manufacture of metal parts, it is necessary to accurately and in detail describe all the parameters of the future product, regardless of the chosen method of metalworking. Today, a variety of technologies are available for ordering, such as CNC turning and milling, welding, bending, high-precision laser cutting and drilling of metal. These methods can create a wide range of flat and dimensional products including bearing housings, bushings, hardware, construction parts, cutting tools, sprockets, molds, and many others. Each of these items requires an accurate drawing, which can be developed either in-house or offered as a separate service by a company specializing in metalworking.
How to order metal products according to drawings: project options
When it is necessary to order a project, the services of an engineer can vary significantly depending on the initial state of product development. Sometimes it is required to produce spare parts from metal with the development of drawing papers from scratch, which implies a full understanding by the performer of the functional features of the part, the place of its application and many other factors. In other cases, the work can be based on an already existing product or sketch.
Such works include:
- Development of a drawing based on an already finished part – this process includes the departure of a specialist to the site to take the necessary measurements and the subsequent creation of an accurate project that reflects all the dimensions and design features of the finished product.
- Having a sketch is more of a design embodiment of an idea that needs to be transformed into a technical document. The sketch serves as a basis for the development of the project, which can then be used for mass production.
- Finalizing the drawing into a full-fledged document – this stage requires revision and refinement of existing design documents, often due to changes in technology or manufacturing requirements. Such revisions may include a change in fabrication methods, for example from casting to welding.
The importance of the drawing in CNC part manufacturing
Manufacturing metal parts on a CNC machine requires an accurate drawing that serves as the basis for developing the sequence of operations to be performed by the machine. Based on this data, the operator can not only determine the necessary machining parameters, but also quickly calculate the cost of the entire order. This makes it possible to optimize the production process and achieve serial production with deep copy identity.
