Tool alignment process of Guangzhou 980td CNC lathe;
1. First, the first step is to return to zero (return to the origin of the machine tool) so as to clear the coordinate data of the last operation. Note: X, Y and Z axes need to be zeroed.
2. Input the command code immediately, make the spindle rotate forward, and keep the moderate speed. Then switch to "handwheel" mode, and operate the machine tool movement by changing the adjustment rate.
3. Gently touch the X-direction tool alignment tool on the right side of the workpiece to reset the relative coordinates of the machine tool; Lift the tool along the Z direction, then move the tool to the left side of the workpiece, descend to the same height as before along the Z direction, and move the tool to gently touch the workpiece to lift the tool.
4. Gently touch the tool in front of the workpiece to align the tool in Y direction and reset the relative coordinates of the machine tool; Lift the tool in the Z direction, then move the tool to the back of the workpiece and descend to the same height as before in the Z direction.
5. Then, move the tool to the surface of the workpiece to be aligned with the zero point in the Z direction, slowly move the tool to make it gently contact with the upper surface of the workpiece, write down the Z direction value in the machine tool coordinate system at this time, and press the (Enter) key to enter the coordinate system.
6. Finally, when the spindle stops rotating, stop the spindle first, move the spindle to a suitable position, and retrieve the machining program. Managers can press the switch to complete the machining center with FANUC system and use multiple knives at the same time.
Extended data:
The function of numerical control system is not only to complete the basic linear and circular interpolation calculation, but also to configure a lot of special software, which can complete many aspects of work, some of which are impossible or difficult to complete by traditional numerical control. CNC system usually has the following main functions:
(1) axis control can control 3, 4 and 5 axes simultaneously. It can achieve higher cutting speed and processing quality.
(2) Tool Offset Compensation Modern CNC systems often have the function of tool radius compensation in three-dimensional straight lines.
(3) Programming function system provides some programming functions. Usually, the color graphic display terminal of the system can be used to manually compile the processing program of plane contour parts composed of straight lines and circular arcs, and the system is equipped with software to automatically calculate the intersection and tangent points of contours.
(4) Parallel operating system can realize two working modes in parallel: machine tool control mode and programming mode.
