They re practically twins. Some might say this about superalloys and titanium, but as with most twins, there are a few subtle differences.

Materials like nickel-base, chrome-base, and iron-base superalloys are extremely heat resistant, even more than titanium, so most of the heat produced during machining is absorbed by the cutting edge.

This can wreak havoc on the cutting tool and cause damage ranging from crater wear, to plastic deformation, to complete tool failure.

Most superalloys are not flammable, so they can be machined with ceramic ....etc

CNC SYSTEMS

INTRODUCTION

Numerical control (NC) is a method employed for controlling the motions of a machine toolslide and its auxiliary functions with input in the form of numerical data. A computer numericalcontrol (CNC) is a microprocessor-based system to store and process the data for the control of slide motions and auxiliary functions of the machine tools. The CNC system is the heart and brain of a CNC machine which enables the operation of various machine members such as slides,spindles, etc. as per the sequence programmed into i ....etc

ADAPTIVE CONTROL SYSTEM WITH KNOWLEDGE SERVER IN INTELLEGENT CNC SYSTEM

ABSTRACT:

In an ideal scenario of intelligent machine tools the human mechanist was almost replaced by the controller. During the last decade many efforts have been made to get closer to this ideal scenario, but the way of information processing within the CNC did not change too much. The paper summarizes the requirements of an intelligent CNC evaluating the advancement of technology in this field using different adaptive control systems. In this paper a low cost ....etc

NC and CNC machines and Control Programming



Motivation and uses

To manufacture complex curved geometries in 2D or 3D was extremely expensive by mechanical means (which usually would require complex jigs to control the cutter motions)

Machining components with repeatable accuracy

Advantages of CNC

Easier to program;
- Easy storage of existing programs;
- Easy to change a program
- Avoids human errors
- NC machines are safer to operate
- Complex geometry is ....etc
