This study presents a method for turning cylindrical worms using universal turning tools. The surface preparation for testing was conducted using a point method, employing V–shaped cutting inserts to turn the worm thread, which has a profile angle of 20 degrees. To facilitate the turning of the thread, we analytically derived a formula to determine the distance from the corner of the insert to the side of the thread at the contact point. Additionally, we presented a theoretical calculation for the height of the roughness profile. The mean absolute error between our predicted Rt roughness parameter and the measured value is 2.8 μm, which results in a mean absolute percentage error of 13.6%. We developed special software to assist in preparing NC code for a numerically controlled machine tool. Ultimately, we obtained a theoretical profile that will be used to assess the size of deviations. The results of the thread profile measurements conducted on a coordinate measuring machine, along with the surface quality evaluation from roughness measurements, classified the worm within the 9th accuracy class. This confirms that our method is appropriate for roughing or semi–finishing operations. The analysis of the results validates the use of this method in machining worm gears, and the findings from our experimental studies align closely with theoretical expectations.
