The design of the prototype is an important step to improve the quality of the prototype. Many factors need to be considered, including the selection of the prototype material, the usability and safety of the prototype structure, the machinability of the prototype parts and the convenience of the prototype maintenance. You should try to be as thorough as possible at the beginning. In short, there are still many places to pay attention to in the production and processing of hand boards. So do you know what needs to be paid attention to in the production and processing of prototypes? Next, let's give a brief introduction to the attack by the Xiehe rapid prototype processing factory.

Prototype production and processing need to pay attention to the following points:

(1) For the formulation of the prototype process route, it can be divided into two processes according to the needs of the workpiece. First process the inner wall of the appearance of the prototype, mill the datum, and then turn it over 180. Clamping, processing the outer surface and the position of the button screen. If the outer surface is processed first, and then the inner wall is processed, it is difficult to position and clamp for secondary processing.

(2) If the wall thickness of the prototype is only 1.5mm, it is easy to deform and break when processing the outer surface. If there is a filler added to the processed cavity for support. This avoids the need to machine through holes for filling with plaster, otherwise it would be difficult to separate the finished product from the filling.

(3) Repair the trimmed surface first, cover the position of the through hole on the surface, and process the entire surface, and then dig grooves to complete the through hole processing, so as to avoid the undulation of the tool path when processing the through hole. Smooth, uneven cutting force and so on.

(4) Remember! The reference truncated angle must be milled out first, so as not to adjust the wrong direction of the blank when flipping and clamping.

(5) Note: During the production process, the cutting must be simulated first, and after the inspection is correct, the processing is carried out and the CNC machining is carried out.

The selection of prototype materials must not only meet the customer's requirements for product quality, but also take into account the cost of the material and its strength within the set period. Of course, it must also be based on the type of prototype, the way it is used, the processing speed, and the main failure mode. and other factors to select materials.

In addition, the various parts on the prototype should have sufficient strength and rigidity to prevent damage and deformation during use, and the fastening parts should have anti-loosening measures to avoid accidental injury to the operator. Scrap or workpiece missiles are not allowed to occur during processing, affecting the operator's attention, or even injuring the operator. In addition, it is necessary to prevent the burrs of the blanking parts from cutting the hands.

The above content is the content that needs to be paid attention to in the production and processing of prototypes. I hope it can be helpful to everyone. If you want to know more about the prototype, please call the Xiehe prototype processing factory, we will serve you wholeheartedly.
