Eliminating Radial Movement in the Turret During Clamping and Unclamping

This shows slight angular movement of the turret when it clamps and unclamps to move to the next station.

Removing tools from the turret is not necessary for re-referencing the turret.

Set Manufacture Password.

Index turret to Position 1.

Go to [Machine], On the MCP, press [JOG] and [REF POINT] and read the angle reported for MQ1. This is your Q-axis.

The Q-axis represents the degree of rotation of the turret. At Position 1, the greater the Q-axis angle is from zero, the more radial movement there is when clamping and unclamping. Position 1 should be nearly or at zero.

Go to [Diagnostic] → [NC/PLC Variable]

Under Variable, select an empty row. Enter DB37.DBX4.7 Select [B] under format.

On the MCP, ensure that both [JOG] and [REF POINT] are active.

Press [Change], change the number from [0] to [1]→ [Input]→[OK] to confirm bit change. The [1] value will immediately change back to [0].

While the turret is still at Position One, go to [Machine]. On the MCP, press [JOG] and [REF POINT] and verify the reported angel for MQ1 is zero.

Index the turret and verify that the radial movement during clamping and unclamping is eliminated.

Power cycle the machine.
