numerical control

a system of controlling an automatic machine by means of a programme of instructions (often COMPUTER based) which relate to the particular operations being performed on a component. Machines which are operated by numerical control usually work with greater speed and accuracy than machines operated by hand and are particularly suited to MASS PRODUCTION OR PRODUCTION LINE manufacture.

Aiming at the above problem, a reliability model parameter's interval estimation method of NC machine tools considering working conditions based on the Bootstrap method is proposed in this paper.
Advantages associated with the usage of NC machines
The RPC SINUMERIK interface allows remote control of NC machines by a PC and has been implemented in an appreciable number of flexible manufacturing systems.
for high accuracy, low friction micro feed quantity wire cut EDM in the category of other NC machine tools.
Two, NC Machine Tool Simulation lets NC programmers simulate selected machine tool paths, determine interferences, modify tool paths or machining operations, and generate ISO code.
Automatic tool wear adjustment is normally also a feature of NC machine tools, but at times this feature is not desired or used.
This machine is a 2 axes NC machine. The simulation results of each manufacturing phase are presented in figure 4.
by a computer becomes a necessity, and only on the basis of acquired data is the drawing preparation and direct generation of CL data for the component production on NC machine possible.
An example would be transferring the data directly from a CAD workstation to the part programs that drive an NC machine. Joseph Harrington, Jr., and others, however, recognized that the problem was far broader and that only enterprise-wide integration would truly unify the highly fragmented computer activities in a manufacturing company.
The advent of numerical controli (NC) in the 19508 is represented by some of the first parts that were' made using an NC machine devised by John Parsons, an inventor from Traverse, Mich., and by a Tape-OMatic drill press from Pratt & Whit- ney (West Hartford, Conn.).
In all cases, the NC machine would start with an appropriately sized block of material selected by the CAD/CAM system.
The modelled volume equals to the origin steel part inside needed tolerances and so it can be used for the producing of new part by means of NC machine. Machining process was simulated in CAM module of software where specific parameters were defined in regard to the tool steel machining.
