The production of functional parts by AM can help us design and manufacture products that can not be manufactured by any other means. Using the flexibility of 3D printing, we can make parts have some performance advantages, such as light weight and high thermal efficiency. We can integrate independent components into a complex overall design, and all of this can be completed in one construction process, and the construction process is usually highly automated, efficient in material utilization, and less in production waste.

However, the manufacturing of material is also defective. With the above advantages, there are also some headaches in the field of additive manufacturing. It is very difficult to finish machining parts for added parts, because they are light in weight and complex in shape. Two characteristics will cause the clamping and vibration of the workpiece, resulting in low production process. In addition, if complex components lack precise post completion correction data, then the alignment of parts is also a problem.

The problem to be solved in this paper is to make the lightweight parts have enough stiffness for effective finishing. We will explore how to use effective workpiece clamping schemes to produce Machinable non rigid parts. We will also introduce how to use the machine tool detection device to align complex parts of the added material, helping us to "find the right parts" in the established shape and correctly process the key datum.

Processing demand

There are many kinds of processing requirements, so adding material or 3D printing process can not process the shape with precise tolerance, especially metal materials. Usually, post-processing is needed to get accurate circular holes and smooth surface, and connect with other parts. However, too light weight often reduces the stiffness of the parts added to manufacturing parts, which means they can not finish the machining process well. The shape of added parts is complex. How to achieve solid holding without causing damage is a difficult problem. Finally, after the forming of the spare parts, it usually needs to be processed into a reference figure. How to install the parts for finishing is a difficult problem.

These problems have many similarities with the challenges faced by the composite and superplastic forming parts manufacturers - that complex shapes may be deformed, and the exact shape must be machined in the position of the deformation. The user can learn the best way to solve the problem of additional manufacturing in other industries.

Case study: microwave catheter

In the problem of manufacturing and processing, the first thing to consider is whether the stiffness of the part is enough to bear the load that must be borne during the process of processing, which leads to a lot of problems. Assuming that we now have a part that can provide sufficient stiffness by design or support, then another important question is how to get data and calibrate our machine tools. There may be some deformation and lack of accurate data in the construction of a complex shaped material, which means that we have to "find the right parts" within the shapes that have been processed. Whether our spare parts can achieve the best five axis calibration is very important.
