Programming source program for machining internal taper thread

My programming source program for machining internal conical threads To machine internal conical threads, several basic steps are involved. The program sequence for machining a conical thread are as follows: 1. Specify the spindle speed and feed rate. Spindle speed and feed rate parameters’must be specified in terms of both the radial component and the axial component of motion. The radial component specifies the rate at which the cutting tool is introduced into the workpiece, while the axial component specifies the rate at which the tool is removed. As a general rule, the spindle speed should be increased along with the feed rate as the diameter decreases. 2. Displace the tool in the axial direction. The tool should be moved along the z-axis of the coordinate system to the point at which the conical thread is to be machined. This downward motion should occur gradually until the predetermined pitch is reached. 3. Orient the cutting tool. The tool must be oriented to the proper tool angle in order to ensure that the helix angle of the thread is correct. The tool must be tilted away from the workpiece to accommodate the proper thread helix angle. 4. Displace the cutting tool radially and axially. The tool must then be moved along the radial and axial axes in order to generate the correct profile for the conical thread. The radial displacement should be proportional to the thread pitch, while the axial displacement should remain constant. The tool will traverse the thread profile in a spiral path. 5. Move the tool along the z-axis. The tool should be moved along the z-axis in order to finish the conical thread. The motion should occur gradually and start at the top of the thread profile and end at the bottom. 6. Make the final adjustments. Once the thread profile is generated, the tool must be adjusted to account for any errors in the helix angle or thread pitch. These adjustments should be made as needed in order to achieve the desired result. 7. Repeat the process as needed. In order to machine multiple threads of the same pattern and helix angle, the process must be repeated as necessary. This same programming source program can be used to machine additional threads. By following this process and specifying the correct parameters for each step, correct and precise conical threads can be produced with the CNC machining process.
