Tool coordinate system

If you want to create a CNC Program, you must know also about tool coordinate system.

dont forget to adjust the tools.

Coordinate system

There are easy ways to remember the coordinate system in programming Cnc.
1. Cartesian Coordinate Systems

2. Right hand rule

Kind of axis coordinate in CNC Machine

Before we go to create a cnc program, we must know that every machine have a axis coordinate.
If the machine only have 3 axis coordinate, then it should be look like this

and axis coordinate in lathe machine, generally look like this

and this

You must know the philosophy of the axis coordinate

Information needed in CNC programming

There are information needed in CNC programming, such as :

1. Preparatory Information: units, incremental or absolute positioning

2. Coordinates: X,Y,Z, RX,RY,RZ

3. Machining Parameters: Feed rate and spindle speed

4. Coolant Control: On/Off, Flood, Mist

5. Tool Control: Tool and tool parameters

6. Cycle Functions: Type of action required

7. Miscellaneous Control: Spindle on/off, direction of rotation, stops for part movement

This information is conveyed to the machine through a set of instructions arranged in a desired sequence – Program
