CNC DNC CAE CIM

CNC: is a software base system in which computer replaces the control unit. Cnc computer’s control only one machine. Cnc is an integrated part of machine. It having lower power processing. It is a modern technique.l

DNC: is an also computer numerical control system, it employed a separate computer. Dnc control more than one machine using local networking. It is located and distance of machine. It having higher processing power. It is traditional one technique. 

CAE: it is defined as the use of computer system for finding the analytical solution for various engineering solution.

CNC milling: has been accepted as the one of the most versatile machine tool used in manufacturing industry. The milling machine are programmed in three axis x,y,z. x axis control the movement of worktable in horizontal in left or right direction and z axis control the vertical tool movement.

CNC EDM: utilize every thin wire (0.02 to 0.03mm) mid-off brass. The wire is work as a electrode. The wire is stressed b/w two roles and the part is orsed by a spark from the wire. Thus the wire cut the part like as a saw to the required profile. The system having wire try system with die electric fluid or water.

Processing in CNC machine: is a computer software, which can be used by a part programming within the fane work of some standard arise analog rule and convention to convey the part program / oblique geometric. Instruction for the tool motion and related information. There are 10 of computer language develop all over the world. But most properly is “APT” is stand for automatic programming tool.

Register: are the small memory devices that can receive and hold and transfer data. Both control unit and earthmatic unit perform their function by using register. Various function of register:

1. Program counter

2. Memory address register

3. Instruction resister

4. Earthmatic logic unit

CIM(Computer Integrated manufacturing): It is defined as the production system which consist of a group of machine connected to gather by an automated material hand line system an operating under computer system.

Type of CIM:

1. Special manufacturing system

2. Flexible manufacturing shell

3. Manufacturing shell

Advantage of CIM:

1. Increases machine utilization.

2. Reduce direct and indirect labor & manufacturing lead time.

3. Flexibility to change & manufacturing.

4. Higher rate of production.

5. Uninterrupted production can be active.

Basic component of CIM:

1. Machine tool and related equipment.

2. Material handling system.

3. Computer system & human labor.

Benefit of CAD: 

1. Improve in engineering productivity lead time.

2. Customer modifications are easily.

3. Faster response to request for the citations.

4. Minimizing the error.

5. Improve accuracy of design.

6. Provide better functional analysis.

7. Designs are more standard.

8. Reduce ruining time.

9. Better knowledge for cost provide.
