Tool setting with a reference tool
● Select a reference tool (e.g., tool #1) and manually cut the workpiece's end face. Record the current Z coordinate and enter it into the system (e.g., Z0).
● Cut the workpiece's outer diameter, measure the outer diameter, and then record the current X coordinate and enter it into the system (e.g., X = diameter).
Tool Setting with a Non-reference Tool:
● After changing tools, manually touch the end face and outer diameter cut by the reference tool, record the current coordinates, and enter them into the system. The system automatically calculates the tool offset.
● Keep the spindle stable during cutting to prevent vibration from affecting accuracy.
● When measuring the outer diameter, use a micrometer to ensure accurate data.
Coordinate Setting Command Method
● The CNC vertical lathe uses trial cuts or a tool setting probe to determine the offset of the workpiece coordinate system origin relative to the machine tool origin.
● For CNC vertical lathes, enter G54-G59 commands in the CNC system to call up the preset coordinate system parameters.
● For batch processing on CNC vertical lathes, pre-set multiple coordinate systems to reduce repeated tool setting time.
● Regularly verify coordinate system parameters on CNC vertical lathes to prevent offset caused by machine vibration or collision.
Tool Setter Application Method
● Touch the CNC vertical lathe tool to the tool setter's positioning point; the system will automatically record the tool position.
● The CNC vertical lathe calculates the tool offset using sensors or software and enters it into the CNC system. ● Regularly calibrate the tool setter on a CNC vertical lathe to ensure it is aligned with the machine coordinate system.
● The tool setter should be installed in a location where vibration is minimal on the CNC vertical lathe to avoid external interference.
Workpiece Offset Setting Method
● Enter the "Workpiece Offset" screen on the CNC system and enter the tool offset (X and Z directions).
● Run the program in MDI mode on the CNC vertical lathe to verify that the offsets are correct.
● Combine the CNC vertical lathe with a trial cut method, first coarsely adjust the offsets, then fine-tune to achieve optimal accuracy.
● Use the "Relative Coordinates" function to monitor the tool position on the CNC vertical lathe in real time to avoid overtravel.
