Turning Stock Transfer

Stock Transfer moves the part between the Main and the Sub-Spindle. There are 2 functions to achieve this.

No toolpath is associated with these strategies. The post processor is responsible for outputting the desired NC code.

To transfer a part from the Main Spindle to a Sub-Spindle, you will use both of these commands. However, if you're not doing a full transfer, you may only want to use one of these functions. You may also use these to hold the part during a Turning Part (cut off) operation. Once you know how both operations work, you can use each function to fit your needs.

Note: Postprocessor modifications may be needed to use these functions on your machine.

A common work flow example for Stock Transfer.

Secondary Spindle Chuck will extend.
The chuck will feed to the clamp depth and grab onto the part.
If it's a bar feed process, a Turning Part toolpath might be used to cut off the part.
Secondary Spindle Return will return to it's home position.

Secondary Spindle Chuck

This function drives the Sub-Spindle up to the Main Spindle at the clearance height, feeds to the depth and clamps onto the part. This is the first part of doing a part Transfer.

Feedrate

Once the Sub-Spindle has moved to the Feed Plane (Clearance), this is the feedrate to move to the Chuck Plane (final depth to grab the part).

Stop Spindle During Chuck

Forces a spindle Stop during the chucking process.

Spindle Speed

If the spindle is not stopped, you can set the RPM to synchronize the 2 spindles.

Spindle Orientation

Allows you to create an angular shift between the 0° reference position of the part. You can enter an angle to shift the second spindle reference.

Use Part Catcher

Enable to activate the part catcher. Only available if your machine is equipt with a parts catcher and your post is written to support a parts catcher.

Dwelling Period

Enter a time for the operation to dwell.

Feed Plane

This is the position the chuck will rapid to, before feeding to the clamping position. The Feed Plane is shown in Orange.

Feed Plane Mode

Set this height to control the reference position for the Offset.

Offset

Sets the distance to shift the Feed Plane.

Chuck Plane

This is the position the chuck will feed to, before clamping the part. The Chuck Plane is shown in Green.

Chuck Plane Mode

Set this height to control the reference position for the Offset.

Offset

Sets the distance to shift the Chuck Plane.

Secondary Spindle Return

This function sends the Sub-Spindle back to it's normal home position. This is the second part of doing a part Transfer.

Feedrate

Once the Sub-Spindle chuck has closed, this is the feedrate to move back to the Feed Plane.

Stop Spindle During Chuck

Forces a spindle Stop during the chucking process.

Spindle Speed

If the spindle is not stopped, you can set the RPM to synchronize the 2 spindles.

Dwelling Period

Enter a time for the operation to dwell.

Open Spindle Chucks

Specifies the conditions of the chucks during the retract process.

Feed Plane

This is the position the chuck will feed to, before returning to the home position.

Feed Plane Mode

Set this height to control the reference position for the Offset.

Offset

Sets the distance to shift the Feed Plane.
