excellent visibility of the cutting operations and easy swarf clearance. The machine should be
capable of cutting steel, brass, aluminium, plastic and wood with appropriate attachments.
The machine should have a integral touch sensitive control panel incorporating illuminated push
buttons allowing the machine to be operated without a computer being connected . An integral
safety emergency stop button is essential .
The main spindle drive should be an AC motor controlled by an inverter drive package with integral
overload safety cut-out.
The axes motors should be DC stepping type controlled by bi-polar chopper drives.
The machine should have full perimeter guarding with fail-safe switches, in the positive (safety)
mode, on all access doors and guards,which stop spindle rotation and axes movements on opening.
The machine should allow, with appropriate optional accessories and software, easy integration with a
Vertical Machining Centre into a CAD/CAM Laboratory or into a Flexible Manufacturing System (FMS
or into a Computer Integrated System (CIM).

        Hammer design
        Pocket torch
        Salt and pepper pots
        Chess set

CAD/CAM Software
The software should include:-
Windows 95 or above compatibility, the software is an integrated suite of powerful CAD/CAM tools
which create G&M code programs conforming to Industrial ISO programming standards.

Computer Aided Design
  The CAD package should provide a number of tools which allows the input of Straight Lines,
  Arcs and Threads to define internal or external profiles.
  Manipulation tools allow existing entities to be moved or deleted and new elements to be added.
  Automatic error checking does not allow illegal entities (not conforming to turning conventions
  and or the tooling available) to be defined.
  Alternatively, component profiles can be imported from a third party CAD package (e.g.
  Autocad) using the DXF file formats.

CAM Processing
  The CAM Processor automatically produces an Error free G&M code listing making optimum use
  of the cutting tools available and assigning feeds, speeds and cut depths appropriate to the
  selected material and the machine tool been used.



Manual Data Input
  Existing G&M Code programs can be edited, or new ones defined using the sophisticated CNC
  editor.
  Blocks can be modified, inserted or deleted with the aid of the on-line programming code help
  facility.
 When inputting new programs, each block entered produces a graphical simulation of the cutter
 path.
 Automatic error checking ensures incomplete blocks and speeds, feeds and cut depths
 inappropriate to the material and machine tool cannot be specified.



G&M Program Import
 Post Processed files can be imported from major CAD/CAM packages.

Graphical Views and Simulations
 The component produced by a program can be viewed in both 2D and 3D. A Zoom and
 cross-sectional view facility allows individual sections of the component to be viewed in more
 detail.
 The manufacture cycle for programs can be simulated in 2D and 3D in either single block mode
 or continuous mode.

Manufacture
 The machines should incorporate Datum Switches, which allow the machine to automatically
 initialize at the start of manufacture. The only user input is the measured length from the front
 face of the chuck jaws to the billet front face. In this way, the machining cycle is initiated
 effortlessly and quickly.
 The machines should incorporate an ergonomically positioned operator’s panel, which controls
 the machine tool functions. This emulates the type of manual control panel found on industrial
 CNC controls.

Off-Line Fanuc Panel Emulation
 This software package can be integrated into the CAD/CAM software suite to allow programs to
 be edited or written using an on-screen emulation of the Fanuc OT Control Operators Panel.
 Manual control of the machine tool and automatic manufacture of programs can be simulated
 using the emulation software.

Administrator (Tutor) Functions
 In administration mode, the following can be modified.
 TOOL Library - Defining of new tools and offset setting.
 CUT Data - This is the information the sophisticated CAM Processor uses to automatically create
 a G&M code program.
 Administrators can Add/Delete materials, change feeds, speeds and cut depths.
 PARK Position - Tool Position for Tool Changes
 UNITS - Sets the units for the Configuration settings - metric or imperial.
