Fixtures are fundamental and crucial elements of any manufacturing process. They are used to hold one or several workpieces in a fixed location securely during various process steps like assembly, bonding, post processing, transport or final quality measurement.
3D printing provides a fast and cost-effective production process especially in the context of low-volumes that are typically given for fixtures and other production aids. Establishing Additive Manufacturing for fixtures results in reduced operational costs, reduced lead times and improved efficiencies of the work floor. Since 3D printing does not require any tooling upfront, tailor-made fixtures can be produced efficiently that serve the respective process step perfectly. The underlying CAD file can be redesigned and reprinted anytime allowing the user to adapt fixtures even last minute or according to any future process iteration.
Several parts are being held at a specific orientation and a stable position to simplify the connection and mounting process.
Subtracting unwanted material to create a desired shape - via turning, drilling and milling. Stability and holding strong forces are very crucial here.
Quality control using CMM or CT require fixtures to hold parts in a specific orientation – covering only minimal surfaces.
When joining two parts together, it is important that they are oriented and aligned properly and stable.
Some manufacturing processes or assembly steps require ex-post inspection for accuracy. Go/No-go fixtures are a simple solution here.
Sensitive parts must be transported safely from one workstation to another. Custom trays can improve these internal logistic processes.
While working at a workstation, lean tool handling is important. Therefore, a shadow board with a good fitting and a clear structure is vital.
