8. DCP-i FUNCTION
(DOOSAN Rotation-axis Center Point Compensation – Intelligence)
8.1 OVERVIEW
This instruction is for the 5-Axis Machining center compensation function to maintain the position
from tool tip to workpiece regardless rotation of axes. The function is designed to perform the
compensation automatically with Touch probe and Datum ball, and to minimize the Error of cutting.

This screen is the main screen that required data for measurement can be inputted and the results of
measurement can be checked. Detailed explanation of the screen are below :
① Displays Relative Coordinates, Absolute Coordinates, Machine Coordinates, Distance to go.
② Set the diameter of ball, Tool Offset Number, the number of measurement of C-axis / A-axis in range of
displayed on right before the measurement.
③ Result of measurement, Measurement error of X-axis / Y-axis / Z-axis will be displayed.
④ Measured error value is saved automatically in the data table when parameter save “Y” is selected.
(When parameter save “N” is selected, No data is saved.)
⑤ Soft Key to return to Package Software Main screen.
⑥ Soft Key to start the TCP measurement.

⑦ Soft Key to move cursor to the right table that data is saved.
⑧ Soft Key to input the saved data in the table to NC.
⑨ Soft Key to “LOCK” the saved measurement data and display “L” mark when this function is activated.
⑩ Soft Key to “UNLOCK” the “LOCK” data and remove “L” mark when this function is activated.
8.3 TCP SETUP GUIDANCE OPERATION
8.3.1 PREPARATION
1. Install the Touch probe set calibration value and Datum ball.
(Calibration must be performed by using Renishaw GUI function.)
2. Exchange the Tool by using Touch probe.
3. Perform REFERENCE RETURN on C and A axes.
8.3.2 OPERATION
1. Press [CUSTOM1] KEY to go to EOP Main menu. And press [DCP-i] Soft Key DCP-i screen is displayed.
2. Move Z-axis, up to 10 - 20mm from stylus of Touch probe to upside of Datum ball with MPG.
3. Enter the diameter of Datum ball, tool offset No. of Touch probe, the number of measurement of C / A axis
as below figure [4].

4. Change the mode to [MEM].
5. Press [TCP MEASURE START] Soft Key. And then press CYCLE START. The measurement will be start
automatically.

6. After the measurement ended up, enter “Y” and push [INPUT] key for corresponding message
“MACHINE PARAMETER TO SAVE OK? PRESS Y OR N!” as below figure [6]. Then parameters will be
saved and compensation value also will be applied automatically.
The screen can’t be changed until “Y” or “N” is inputted.

8.3.3 MEASUREMENT DATA ‘SAVE’, ‘LOAD’, ‘LOCK’ FUNCTION
1. [DATA TABLE LIST] is being after the measurement, the data is saved automatically if “Y” is inputted.
2. When [ DATA TABLE LIST] soft key is pushed, the cursor is moved to the data table.
3. The data line can be selected by moving the cursor and when the [LOAD] soft key is pushed, the
saved parameter can be inputted by selecting “Y”, “N”. (The screen can’t be changed until “Y” or “N” is
inputted.)
4. When [LOCK] soft key is pushed, the selected data can be protected. And “L” mark is displayed in the
data line.
5. If [UNLOCK] soft key is pushed, the protected data can be deleted. And “L” mark is removed in the
data line.
