1, try cutting knife



Trial cutting is mainly used to establish the machining coordinate system. After the workpiece is installed, in order to be able to machine the required workpiece, the programming origin is set as the machining origin, and the machining coordinate system is established to determine the relative position of the tool and the workpiece, so that the tool moves according to the programmed trajectory, and the final machining is performed. The required parts.



The steps of trial cutting are:



(1) Select the manual operation mode of the machine;

(2) Start the spindle, try to cut the outer circle of the workpiece and keep the X direction from moving;

(3) Stop the spindle and measure the outer diameter value of the workpiece;

(4) Select the MDI operation mode of the machine tool;

(5) Press the "off set sitting" button;

(6) Press the "Coordinate system" softkey at the bottom of the screen;

(7) The cursor moves to "G54";

(8) Enter X and the measured diameter value;

(9) Press the "Measure" softkey at the bottom of the screen;

(10) Start the spindle and test the end face of the workpiece to keep the Z direction from moving;

2, machine tool counter knife



External tool setting tool The tool setting tool needs to fix the micro tool setting tool on the lathe to establish the compensation value between the tools. However, because there will be a certain difference in the size of the tool, the coordinate values ​​of the tool points in the machine will be different. If the compensation value between the tools is not set, the same size cannot be processed when the same program is run. To ensure that the same program is run, if different tools are used to obtain the same size, the compensation between tools must be established. .



The steps of the knife countermeasure on the outside of the machine mainly include:



(1) Move the reference knife so that the knife point is aligned with the center of the crosshair of the microscope;

(2) Clear the relative position of the reference knife at this point, the specific operation is to select the relative position display;

(3) Clear the tool compensation value by pressing the “off set sitting” button. Press the “Adjustment” softkey at the bottom of the screen and select “Shape” to enter the tool compensation number corresponding to the reference knife. Xo, Zo;

(4) Select the manual operation mode of the machine tool, remove the tool holder and change the tool;

(5) Make the knife point at the center of the crosshair of the microscope;

(6) Select the machine's MDI operating mode;

(7) Set the tool offset value. The specific operation is to press the “offset sitting” button, press the “Adjustment” softkey at the bottom of the screen, select “Shape”, and input X, Z on the corresponding tool offset number;

(8) Remove the tool post and execute the automatic tool change command.
