AB  -  MAKER: Converting the Sketch of an Artefact into a Composite Bezier Curve           and Producing it in the Boxford Milling MachineIntroduction to Computer Aided Manufacturing Course, is taught to the SeniorMechanical Engineering students at X university. Two of its course outcomes are (i)Students   will   be   able   to   apply   the   knowledge   of   mathematics   and   engineering  science  to  model  engineering  shapes  using  parametric  curves  and  (ii)  Students  are  able  to  integrate  different  domain  knowledge  to  generate,  evaluate,  and  implement  part  programming. This project is aimed at these two outcomes. As part of the courseBezier curves are taught and students become familiar with the analytical part ofcomposite Bezier curves. On the manufacturing side, students start with manualprogramming to understand and interpret codes and then CAM packages areintroduced. Practical exercises are given in the class to enrich the learning experiencelinking the theory and its implementation in practice. It is often a challenge to sketchsomething on a paper and convert it and as a CAD profile to generate NC code for itsmanufacture. This paper and artefact demonstrates such a conversion and manufacturecarried out by the students as the term project. The students worked in a group of fourand were given an outline sketch as given in Figure 1 showing the different featuresthat could go into the product. They were asked to come up with conceptual sketchesand choose one. The chosen concept was drawn on a graph paper to the full scale. Theresulting sketch (cross section of the artefact) was then broken into curve segmentsand the individual segments were modelled with due consideration for the boundaryconditions. Two approaches were taken to model the curves. In the first approachCorelDraw software was used for modelling and in the second approach the curveswere modelled mathematically. The result from this design part was a collection ofcurve segments with starting and finishing points and their control points. TheBoxford Milling machine is a bench type machine for small jobs done in plastic orAluminium. Curves are modelled in it as Bezier curves and control points and startingand finishing points are the required inputs. The resulting artefact is shown in Figure2. The student participation was excellent and every group completed the project.                     Tower for University Logo            U                                                 Hole for a clock Insert Dia 37.5 mm             E          UA                                                                Department NameOverallHeight45 mm                                                                              Overall Width                                                                              Not more than 50 mm                          Overall Length 115 mm                                                                                                                                              Figure  1                                                                                                                                                                                                               Figure  2
