Cutting Forces in Milling of Carbon Fibre Reinforced Plastics

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining any excessive cutting forces have to be avoided in order to prevent any waste product in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select process parameters necessary

Effect of fiber orientations on surface grinding process

The machining mechanism of woven ceramic matrix composites is one of the most challenging problems in composite application.
