Tool Change

A tool change QPushButton, with a QComboBox to select the tool number to change to, is done with QPushButton named tool_change_pb and a QComboBox named tool_change_cb. The tool change combobox will automatically be populated with all the tools found in the tool table.

Tool Change Controls

Control Function	Object Type	Object Name
Tool Change	QPushButton	tool_change_pb
Tool Selector	QComboBox	tool_change_cb

To add the description of the tools to the tool change combo box add a Dynamic Property named option and set the value to description.

The description from the tool table will be appended to the tool number.

If you have limited space you can define the tool prefix by adding a Dynamic Property named prefix and set the value to the prefix you want.

The tool number will follow the prefix.

Note

Only one option can be used, if option is found it is used and prefix will be ignored.

Manual Tool Change

The manual tool change requires that the iocontrol.0.tool-prepared and the iocontrol.0.tool-changed be toggled on after inserting the tool into the spindle. A QPushButton with an object name of tool_changed_pb can be used in place of the hal_manualtoolchange. You need to make it a HAL button and connect the output to both iocontrol.0.tool-prepared and iocontrol.0.tool-changed

net manual-tool-changed iocontrol.0.tool-prepared flexhal.tool-changed
net manual-tool-changed iocontrol.0.tool-changed

Note

You need to hold the button down for about 2 seconds or until you see the tool is changed.

Manual Tool Change requires at least the following HAL code in the main hal file if the hal connections are not done as above.

# manual tool change
loadusr -W hal_manualtoolchange
net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

Tool Change Button

Tool change QPushButtons can be used to change tools without a spinbox by adding up to 99 QPushButtons named tool_change_pb_n. With n being the number of the tool you wish to change to using that button

Tool Change Buttons

Control Function	Object Type	Object Name
Tool Change Button	QPushButton	tool_change_pb_(n)

Tool Touchoff

To touch-off a tool to an axis, use a tool-touch-off QPushButton and a QLineEdit to enter the value of the touch off.

Tool Touchoff Controls

Control Function	Object Type	Object Name
Tool Touch Off Value	QLineEdit	tool_touchoff_le
Tool Touch Off	QPushButton	tool_touchoff_(axis letter)

Optionally you can have a QLineEdit for each axis for tool touch off. Add a Dynamic Property named source to the tool touch off button and set the value to the name of the QLineEdit that is the source for that touch off button.

Tool touch off QLineEdit for each axis.

Current Tool Status

Current Tool status of the tool loaded in the spindle. All the labels can have a Dynamic Property called precision with the number of digits you wish to show. The tool_id_lb and the tool_orientation_lb are integers.

Tool Table Status Labels

tool_id_lb	tool_xoffset_lb	tool_yoffset_lb
tool_zoffset_lb	tool_aoffset_lb	tool_boffset_lb
tool_coffset_lb	tool_uoffset_lb	tool_voffset_lb
tool_woffset_lb	tool_diameter_lb	tool_frontangle_lb
tool_backangle_lb	tool_orientation_lb
