The application of cryogenics in manufacturing has previously received significant attention in supporting manufacturing processes. This paper explores the continued application of cryogenic manufacturing for producing personalised products. This paper presents the novel concept of cryogenic CNC machining of elastomers and the development of a process control system for cryogenic CNC machining. The control process is illustrated alongside material dependent machining data and example soft elastomer machined parts. An enhancement to the process is also detailed within a closed loop thermally monitored cryogenic CNC machining facility.
