What trends are currently shaping metalworking?

The current 2022 trends are extrapolations of longer-term developments. To name a few examples: The reduction of batch sizes down to batch size 1 remains important. Process integration will then play an important role, so that several manufacturing processes can be carried out with one clamping of a workpiece, for example. The expansion of connectivity, i.e. networking on the store floor and with the company's IT, is key. Beyond the technical level, this also involves applications that generate real added value from this networking. Plant operation will also play an important role. On the one hand, processes are becoming increasingly complex, while on the other, it is becoming more and more difficult to find highly trained machine operators to control these systems. This is also important in international markets, where the level of training may be lower.

What are the consequences of the transition from combustion engines to electric motors in the automotive industry?

The transformation is currently underway, but is far from complete. Important issues such as the charging infrastructure or the sustainable production of batteries have not yet been resolved and are not trivial. It has long been known that an electric vehicle requires fewer machined components than a combustion engine with a gearbox, but the changeover also offers opportunities for mechanical and plant engineering, for example when setting up new production chains.

What role will additive processes play in metalworking in the future?

Additive manufacturing has undergone rapid development in recent years. The corresponding processes are certainly a good option when it comes to orders with small batch sizes in certain sectors such as medical technology or aircraft construction, i.e. sectors where the high costs pay off. However, it is also a fact that in series production, the classic production method of casting and subsequent machining is significantly more cost-effective. This is why additive manufacturing currently only accounts for a very small proportion of the production volume in metal processing. All indicators suggest that this will remain the case in the longer term. To come back to the initial question, one current trend is definitely the integration of additive manufacturing into the process chain.
