The use of technology to enhance learning opportunities is increasing and interventions such as screencasting can have benefits in providing the student with a flexible learning resource. Within this study, a screencast tutorial was produced for engineering students to teach the process of modelling laminated materials within the commercial finite element software, ANSYS. The effectiveness of the screencast was assessed using an anonymous online questionnaire and small focus group discussion. Overall, feedback from students was positive and found that the majority of students preferred to use a dual learning approach by using the screencast along with an accompanying PDF step-by-step guide. It was also evident from both questionnaire and focus group responses that the instructor–learner interaction was still regarded by the students as an important aspect of the course delivery; especially for teaching advanced concepts when using finite element software.

Carbon fibre composites are a key component of aircraft structures because of their enhanced material properties such as favourable strength to weight ratios when compared to metal alloys. During the assembly process of an aircraft, carbon fibre components are joined to other structures using rivets, bolts, and fasteners, and as part of the joining process, the components will need to be machined or drilled. Unlike metal alloys, composites are sensitive to heat and are vulnerable to internal structural damage from machining tools. They are also susceptible to a reduction in strength when fibres are exposed to moisture. In the machining process, carbon fibre composites may be drilled using oils to lubricate carbide machining tools. In this study, a description of the experimental apparatus is provided along with an investigation to determine the influence synthetic biodegradable lubricating oil has on drill rotational speed, drilling load, and drilling temperature when using a pneumatic drill to machine carbon fibre composite material.
