Item Open Access Drilling system design project 1967: final report of frame design committee(College of Aeronautics, 1967) Sutcliffe, R. S.; Morrison, W.This report outlines the recommendations of the Frame Design Committee for the final design of the machine, each major part of the structure being considered individually in the following sections : 1. Worktables 2. Guide and Slideways 3. Drill Head Support Structure 4. Swarf Disposal and Coolant Supply 5. General ConstructionItem Open Access Manufacturing techniques using dycril(College of Aeronautics, 1967) Morrison, W.Fluidic elements are manufactured in various ways such as injection moulding, epoxy casting and from photo-sensitive ceramic and plastics. Most of the initial work on elements has been carried out using Dycril because of its ease in processing and the equipment required is fairly cheap and simple. Many companies have then developed satisfactory designs using Dycril and used them as ‘masters' in other production processes. Most users of Dycril have reported that nozzle widths of less than 0.015in cannot be satisfactorily etched from 0.040in thick Dycril. Various methods of etching have been tried at Cranfield and this report outlines some of the difficulties encountered and suggests a standard pattern to be followed from the drawings of the master at ten times full size through to the complete element.
