Setting Stock-Chuck

This command allows the calculation of the position of stock in the chuck, especially useful for Bar Turning.

We calculate the distance between the chuck nose and the end of the part.

For this, some values are recovered in the part and others are calculated:

• We have a field for safety distance (S) if the user wants to move the position.

• We analyze stock and part to get the lengths (PL) and Facing allowance (FA).

• We read the parting cycle to recover tool width(TW) and allowance (PA).

All that information is displayed in the dialog and we calculate the result Position of Stock/Spindle (SL). 

There is also a treatment of mistakes:

• We display information to understand why the result is incorrect.

• The parting values are greyed out if the cycle does exist.

When we validate the dialog, the value is automatically written in the dialog area.

This value can be considered as the minimum position necessary to machine correctly the part.

For the ML value, we read the machine kinematics for the distance of sliding headstock. It must be defined in maxi position in the MCG file to be calculated correctly.
