Overview[edit | edit source]
Equipment are physical assets within a factory cell that provide external stimuli to the system. Their purpose is dependent on the stage of processing they are intended for. For example, a hot press is a piece of equipment that may be used to cure a composite, thermoform, or do both. In that regard, a hot press is a piece of equipment that may be used during thermal transformation and/or material deposition. Together, the equipment and tooling represent the system boundary conditions with respect to the part. To truly define a process step, one must understand which equipment can be used and how it should be used. In the MSTEP approach, as used throughout the KPC, equipment is one of the four classes that define a process step.
In order to understand which equipment may be used for a given process step, navigate to the factory process flow page, where links to general processing steps are included. Each process step lists and links out to the equipment that may be used for that step.
Alternatively, if you know which equipment you are interested in learning more about, navigate to explore this area further at the bottom of this page. Here, you'll find an alphabetical list of all equipment pages on the KPC. To learn about any of the equipment, click on the appropriate link.
To learn more about equipment parameters navigate to the following link (note that more information is included in the level II tab).

Welcome
Welcome to the CKN Knowledge in Practice Centre (KPC). The KPC is a resource for learning and applying scientific knowledge to the practice of composites manufacturing. As you navigate around the KPC, refer back to the information on this right-hand pane as a resource for understanding the intricacies of composites processing and why the KPC is laid out in the way that it is. The following video explains the KPC approach:
Understanding Composites Processing
The Knowledge in Practice Centre (KPC) is centered around a structured method of thinking about composite material manufacturing. From the top down, the heirarchy consists of:
- The factory
- Factory cells and/or the factory layout
- Process steps (embodied in the factory process flow) consisting of:
The way that the material, shape, tooling & consumables and equipment (abbreviated as MSTE) interact with each other during a process step is critical to the outcome of the manufacturing step, and ultimately critical to the quality of the finished part. The interactions between MSTE during a process step can be numerous and complex, but the Knowledge in Practice Centre aims to make you aware of these interactions, understand how one parameter affects another, and understand how to analyze the problem using a systems based approach. Using this approach, the factory can then be developed with a complete understanding and control of all interactions.
Interrelationship of Function, Shape, Material & Process
Design for manufacturing is critical to ensuring the producibility of a part. Trouble arises when it is considered too late or not at all in the design process. Conversely, process design (controlling the interactions between shape, material, tooling & consumables and equipment to achieve a desired outcome) must always consider the shape and material of the part. Ashby has developed and popularized the approach linking design (function) to the choice of material and shape, which influence the process selected and vice versa, as shown below:
Within the Knowledge in Practice Centre the same methodology is applied but the process is more fully defined by also explicitly calling out the equipment and tooling & consumables. Note that in common usage, a process which consists of many steps can be arbitrarily defined by just one step, e.g. "spray-up". Though convenient, this can be misleading.
Workflows
The KPC's Practice and Case Study volumes consist of three types of workflows:
- Development - Analyzing the interactions between MSTE in the process steps to make decisions on processing parameters and understanding how the process steps and factory cells fit within the factory.
- Troubleshooting - Guiding you to possible causes of processing issues affecting either cost, rate or quality and directing you to the most appropriate development workflow to improve the process
- Optimization - An expansion on the development workflows where a larger number of options are considered to achieve the best mixture of cost, rate & quality for your application.
