The moving direction of the pulling shaft is negative direction to the left, and positive direction to the right
The Y-axis of the cutting head moves to the left is positive, and to the right is negative
Function Application Background
The tube is generally very long. At present, there are many rear chucks on the market that move the tube from the direction of the feed axis, which requires a long Y-axis travel. Some customers have designed the machine tool with cutting head that can segment the tube. The tube can be cut in sections to reduce the size of the machine tool to achieve the purpose of cutting long tubes. That is to say, it is possible to cut long tubes with a small machine tool. Based on this background, the special pulling function has been developed.
Determination of Machine Coordinate System and Direction
No matter what kind of machine tool, the machine coordinate system and direction are clear and fixed. The following picture is for reference:

Detailed Explanation of Special Pulling Function
Machining Process
Parameter Configuration
According to different model configuration parameters and edit process actions.
Operation Steps:
Enter the configuration console and configuration entry: C:\Program Files\Weihong\NcStudio\Bin. Find NcConfig.
According to different models and device types, configure parameters and configure related actions in flow edit:
In the software, configure the function parameters
Parameter interpretation:
Pull shaft: The single Y pulling model defaults to Y, no need to change.
Pull speed: The speed of the Y-axis when pull material is different from the speed of the Y-axis.
Pull accelerated: The acceleration of the Y-axis when pull material is different from the G00 acceleration of the Y-axis.
Effective area: The maximum range for machining a single primitive. For example, the effective machining area is 100, and if the length of a certain contour is greater than 100, it will not be machined.
Truncation area: The maximum range from the cutoff line to the upper limit of the Y-axis. When this function is turned on, the cutoff line can be cut off close to the chuck, which is more stable.
Tail length: The distance from the clamped tube to the cutting head when the rear chuck travels to the maximum Y travel.
Clamp length: This parameter is meaningless for single Y pushing model. Is 0.
Slip distance: After each pulling, the tube fittings will have a certain length error due to external factors. This parameter can be used to improve the length error and be set according to the actual situation.
Machine efficiency first: The material pulling time is less, and the machining efficiency is relatively high, but because the pulling is triggered during cutting, the relative accuracy is reduced.
Part precision first: There are many times of pulling, and the machining efficiency is low, but it can ensure that materials will not be pulled during cutting.
Know tube length pull mode: The tube length is fixed, use the tube length parameters and drawings to determine whether to start machining.
Tube length: Cut the length of the tube, this option does not take effect when the indeterminate length tube mode is selected.
Unknow tube length pull mode: It is used when the length of the tube is not fixed, and it is judged whether the machining can be continued according to the limit port of the pull material. This function can only be selected after the pull limit is configured. The port configuration entry is as follows:
Check enable pull tube, and the pull tube function will take effect.
Centering after pull: After checking this option, the centering will be performed automatically after each pull.
Single Y Pushing (Chuck Type)
Find the chuck parameters and configure the chuck jaw parameters:
Configure related actions in flow edit:
The following is only the basic configuration. If there are other actions that need to be configured, they can be freely configured in the flow edit.
Single Y Pushing (Chuck Device Type)
Find the clamp unit setting and configure related parameters:
Position Controlled Device:
Clamping minimum tube length: After the pulling function is stopped, the maximum distance that the clamping plate can be opened to avoid interference between the tube and the clamping device.
Extended axis: Select the servo controlled axis for pulling.
Device shield input port, servo pulling can not be configured.
IO Control Device:
Device shield input port: When there is a signal at this port, the clamping plate is always in the open position and cannot be clamped.

Precautions for Using the Special Pull Material Function
The machining length of a single primitive cannot exceed the effective machining area.
Forward and backward across primitives are not supported.
The pull material shaft of the double Y pulling and pushing models is the extension axis, not the Y-axis.
For rear chuck pushing models, the parameter of pulling clamping length is meaningless and can be directly set to 0.
