If you do not use the pull tube function after modifying the parameters, uncheck Enable Pull Tube.
Set parameters. The parameters are described as follows:
Please refer to the schematic diagram of the Pull Tube dialog box.
Parameter | Description |
---|---|
--- | --- |
---- | ---- |
Pull axis | Select different pull axis according to different machine tool designs: ▪ Y axis: The rear chuck pusher, that is, the model with the cutting head stationary and the rear chuck driving the tube movement. ▪ Extended axis: The front chuck pull tube machine tool, that is, the machine with cutting head moving and tube not moving. |
Pull speed | The speed at which the tube is pulled on the Y axis. |
---------- | ---------------------------------------------------- |
Pull accelerated | The acceleration of tube pulling on the Y axis. |
Effective area | ▪ When the rear chuck is clamped at one end, the machining accuracy of the front end of the tube is poor, ensuring that all graphics are cut in this area. ▪ The length of a single part to be machined cannot exceed this parameter. If it exceeds this parameter, it cannot be machined. ▪ Generally about 100 mm. ▪ The actual position is, [upper limit, upper limit - effective area] For example, if the upper limit is 3000, the actual machining position is 2900-3000. |
Truncation area | Under the single end clamping state of the rear chuck, the machining accuracy of the front end of the tube is poor, so that all truncation lines are cut in this area. |
Tail length | When the Y axis is at the upper limit, the distance from the cutting head to the end of the tube when the tube can be clamped. |
Clamp length | It shall be set according to the position of the collet to prevent clamping. ▪ The collet extends beyond the left end of the cutting head and is set to 0. ▪ The collet is located flush with the cutting head and set to a positive value, generally 10-20 mm. |
Slip distance | Supplementary distance given to prevent skidding during pull tube. |
Pull strategy | ▪ Machining efficiency first: Ensure the machining efficiency, and reduce the number of pull tube as much as possible. ▪ Part precision first: Try to ensure that the cutting of a single part is completed after once pull tube. |
Pull mode | ▪ Know tube length pull mode: This mode is selected when the length of the tube to be cut is known. ▪ Unknow tube length pull mode: This mode is selected when the length of the tube to be cut is unknown. Note: This option can be selected only after the port Pull limit is configured in the ncConfig application. |
Tube length | The length of the tube to be machined. It takes effect when the pull mode is Know Tube Length Pull Mode. |
Check as needed:
- Enable Pull Tube: If you do not use the pull tube function after modifying the parameters, uncheck Enable Pull Tube.
- Centering after Pull.
Click Confirm to complete the setting.
