For example, suppose you want to machine the workpiece, such as shown in the figure below in the NC lathe-turning, whether the finished drawing street, to confirm.

①Attach "point finder L" to the tool post and hit it on the reference surface. Operate the pulse handle so that the tip of the stylus hits the reference surface and the LED lights up. If the LED is lit, it is the sign that the stylus touches the reference plane.	②Reset the Z axis of "0.000" display on the CRT screen with this as the reference plane.
③Operate the pulse handle again and then measure the depth of the hole of φ60. At the position where the LED is lit, confirm the Z axis coordinates. This value represents the depth. The bottom screen shows the hole depth of 20 mm.	④Next, measure the depth of the hole of φ40. When the tip of the stylus comes into contact with the surface of the hole, the LED lights, this value is the measurement value of the Z axis.It is possible to measure the depth of 80 mm. of the hole which can not be measured with the caliper and Depth caliper with an accuracy of 1 μm.

①Move the X axis in the - direction and put it in the front position (Z: -10.000 from the end face), place the X axis in front of - direction and reset the X axis at the position where the LED lights up.	②Move the X axis in the + direction and stop at the point where the LED emits light. X: 112.000 was displayed. 112.000 / 2 = 56.000 (Lathe is 2Xdoubled) 56.000 + 4.000 (diameter of stylus) = 60.000 (inner diameter size) In case the stylus of the point finder L does not match the axis center the inner diameter is displayed small. Check with the cylinder gauge and correct the error.
If the 0.1 mm center is misaligned, the X axis of the monitor will be displayed as 111.9992. 111.9992 (It is 2Xdoubled on the monitor) ÷ 2 = φ 55.9996 The actual diameter is φ55.9996 + φ4.000 = 59.9996. If the 1 mm center is misaligned, the X axis of the monitor will be displayed as 111.928. Please correct 0.036 mm.

①Put the stylus of the point finder L to an arbitrary point and reset the coordinates of the X and Z axis monitor screen.	②Apply the stylus to the position you want to measure. At the position where the LED is lit, the trigonometric function tan θ = X/Z is obtained from the coordinates of the monitor using a scientific calculator.
③Since the X axis 10.095 of the monitor is the diameter display, change it to 1/2 and change it to 5.045. The Z axis of the monitor is 30.000 From tan ϴ= 5.045/30, ϴ =9.5506 One side angle ϴis 9°33'03'.
