Machining slots,ng the component show the slots as single lines, 25 mm long (that is, the centre line of the slots will represent the line that the centre of the cutter will take). Select the tool change position and define the toolpath for machining the outside profile as in previous exercises, using a 12 mm dia cutter.

Atomic Scale Friction PhenomenaCNC (computer numerical control) and CAD/CAM (integrated computer-aided draughting and manufacture) are essential elements in many industrial processes. The assignments in this workbook will provide a broad range of practical experiences which represent a valuable foundation to the successful application of this technology.

Nanotribology and NanomechanicsAxial definitions represent the linear movements of machine slides, which may be assigned X, Y and Z depending upon the type of machine. When using vertical milling machines, X and Y represent horizontal movements of the table, whereas in turning the tool movements are X and Z. In either case, precisely controlled linear movements are achieved.

Manuel L. B. Palacio,Bharat BhushanOne of the tasks of the setter/operator is to position the component datum and the tools that are going to be used for machining a program. The programmer cannot always specify certain information such as the exact distance of the component datum from the machine datum, or the precise diameters or lengths of the tools to be used.

Friction and Wear on the Atomic ScaleA CNC program is a set of instructions that is read by the machine tool computer system to control machine slide movements, tool movements and additional miscellaneous functions. There are two types of CNC programming: .. Most CNC machines use word address format, mainly for historical reasons — many of the first machines used this type of format.

Dynamic Modes of Atomic Force MicroscopyWhen you use a CAM system, you need to set up some additional parameters in the initial start-up procedure, over and above those required by a CAD system (discussed in Learning Assignment 9). These parameters relate to the ultimate generation of a CNC program to machine the drawn component and may include the following:
