This paper focuses on manufacturing of ‘Hybrid Microsystems’. Manufacturing of microsystems for niche markets, mainly sensors and actuators, usually struggles with the application of manual- or automated manufacturing. If automated production is applied, it is mostly done with reconfigurable manufacturing equipment. Reconfigurable equipment has been designed to meet rapid adaption in structure, as well as in hardware and software components. In this paper, a new reconfigurable manufacturing approach is used to meet the production requirements for this market segment. The solution combines hard- and software to optimize for flexibility and cost-effectiveness. The system uses small machines, so called ‘Equiplets’, each replacing one or two operators. The equiplets are placed in a ‘Manufacturing Grid’. When using grid manufacturing in combination with equiplets, the production floor can be reconfigured in a more flexible and agile manner. The investigations addresses cost modelling to determine the best way to transfer parts through the grid manufacturing process. Directly coupled production systems are compared to systems with buffers between the manufacturing stations. Though buffers require extra investments, the gain in uptime of buffered systems is in many cases large enough to justify the investments.

The energy demand that has played a minor role in the process design until now becomes more and more important at present. However, there is a lack of systematic support for the manufacturing engineer for this task. Therefore, an approach is shown how to map metal cutting processes with geometrically defined cutting edge with the help of mathematical models. On the basis of these models it is shown how to design a process in the valid range of the process parameters under consideration of the energy demand. In addition, the handling of the data needed for process design is explained. The approach describes how to provide all product and process data by the integrated product model mapped with the Standard for Exchange of Product Model Data.

This paper studies short-term production planning in multi-item production-inventory systems. In short-term planning we study the delays caused by frozen schedules and planning intervals. We consider three different systems that are here called the machining subcontractor, the electrical machine company, and the assembly factory. Each of these has its own special characteristics. The subcontractor has several batching delays caused by setups, the electrical machine company ships products periodically, and the assembly factory has long production times and a long shipment time for finished products. We study how these characteristics affect their short-term production planning. Simulation results show how the electrical machine company has the most noticeable advantage from planning that does not have any delays.

Industrial requirements for automation of small parts assembly operations are driving technology into the direction of scalable robotic automation, suitable for operation in shared environments with human workers and exhibiting highest flexibility and ease of use. One of the challenges is developing solutions for personnel safety under these conditions. This paper discusses both the presently viable approaches to risk assessment for collaborative robots and a more detailed future methodology that will be better able to resolve the relevant low-level injury risks.
