Tool Setting Method For BT-150D 4-axis CNC Tool Grinder
At present, the high-end CNC tool grinding machine is developing in the direction of four-axis control. The workpiece can finish with multi-faced profile machining in one clamping. This is the four-axis CNC machine tool, which will become the trend of development and the overlord of the machining industry. Enterprises must install equipment. The Demina machining center has four axes: A-axis, C-axis, and XY. The A-axis and C-axis can combine with the XY three-axis to process complex spatial surfaces. This allows the workpiece to be subdivided into arbitrary angles. Out of the inclined surface, inclined holes, etc., can process the complex workpiece.
Tool setting method for 4-axis CNC tool grinding machine
1. Tool setting of CNC milling machine: Assume that the part is the asymmetrical part, and the blank has been measured to length L1 and width L2. The diameter of the flat end mill has also measured. After the workpiece is clamped on the milling machine table, it is manually operated. The specific steps are as follows.
Manual tool setting: first make the tool close to the left side of the workpiece (using jog operation to start with micro-cutting), press the set programming zero key, and the CRT shows X0, Y0, Z0. Then Complete the programming zero settings in the X-direction. Then move the tool closer to the front side of the workpiece, keep the tool Y direction, and return the tool X. When the X coordinate value of the CRT is 0, press the programming zero setting button to complete the programming zero settings in the X and Y directions.
Finally, raise the Z-axis and move the tool. Considering the existence of the milling cutter radius, when the X coordinate value is displayed on the CRT (L1/2 + milling cutter radius) and the coordinate value of Y is (L2/2+ milling cutter radius). Move the bottom of the milling cutter closer to the upper surface of the workpiece and press the programmed zero setting button. The X, Y, and Z coordinate values on the CRT screen are cleared to zero (ie, X0, Y0, Z0). The system has completed the programming zero setting function. The cutter point of the milling cutter is set on the center of symmetry of the workpiece. That is the workpiece origin of the workpiece coordinate system.
Set the workpiece coordinate system: At this point, the current position of the tool (the tool point of the milling cutter) is at the programmed zero points (ie the workpiece origin). Due to the manual trial cutting method, the adjustment is simple, reliable, and economical. So it is widely used.
2. The toolset of the CNC lathe. The method of tool setting for CNC lathe is basically the same. First, after the workpiece is clamped on the three-jaw chuck, it is manually operated. The specific steps are as follows.
(1). Try cutting the knife first with the selected tool to the outer surface of the workpiece. Keep the X dimension unchanged, Z direction retract, press the programming zero key, CRT screen display X, Z coordinate value Clear to zero (ie X0, Z0). Then, stop the spindle and measure the diameter D of the workpiece. Then, the workpiece end face is cut. When the X coordinate value displayed on the CRT is -(D/2), press the set programming zero key. The X and Z coordinate values on the CRT screen are cleared to zero (ie, X0, Z0). The setting function of the programming zero points is completed inside the system.
(2) Establishing the workpiece coordinate system The current position of the tool nose (tool location of the turning tool) is at the programmed zero points (ie the workpiece origin).
(3). Reference point operation Use ZERO (refer to the reference point) way to return to the reference point operation, establish a coordinate system. At this time, the coordinate value of the current position of the tool holder center (tool reference point) in the coordinate system will be displayed on the CRT.
