Hi Friends..
We have a Bridgeport VMC 760/16 with Heidenhain TNC 2500 control and Siemens drives machine.
Whenever we try to change tool, The tool change happens like this.
1. Z-Axis moves to M25 position(Position A) +55 as set in the Machine Parameters.
2. Then it comes back to tool change position(Position B) -55 as set in the machine parameters with orientation
3. When it reaches de-clamps and the Z-Axis moves to position A carrying tool.
4. Then magazine rotates for the desired tool.
5. This is the time where problem rises, as soon as called tool comes in the magazine it stops and the tool clamps on position A and magazine returns to its home position whereas the Z-Axis should come to position B and then it should clamp the tool.
and then spindle starts rotating and it comes to the cutting position with the same tool it had before tool change. That means the tool doesn't change
M/c always goes in tool change cycle but it doesn't change the tool...
I have checked the Machine parameters they are as they where before when machine was running okay.
Please help me here...
