Computer Numerically Controlled (CNC) LABORATORY
The DIME labs also include a Computer Numerically Controlled (CNC) lab. This lab is used to hold lab
sessions on this subject and also to machine parts required for students’ projects and from other
requestors at university. In this lab, copper electrodes required for the die sinking machine are also
machined. The lab facilities include two vertical milling machines: Bridgeport Series 1 Interact with a
Heidenhain TNC 145 controller (2.5 axis) and a Cincinnati Arrow 500 vertical machining centre with
Siemens Acramatic 2100 controller (3 axis). There is also a high speed attachment that can provide a
spindle speed of 25000 rpm. Such speeds are required to provide optimum cutting conditions when
using small cutters.
