Present-day catalogues of tool manufacturers do not contain information on milling cutters for planetary milling of metric buttress threads with nominal pitches on computer numerical control (CNC) machines. This paper presents the results of theoretical and experimental investigation of buttress threads cutting on 3-axis CNC machines. The theoretical investigation is based on the kinematic method of envelope determination. This analytical solution has been verified by the solid modelling method and experiments. It has been proven that standard metric buttress threads with nominal pitches cannot be cut by planetary milling on the 3-axis CNC machines. At the same time, metric buttress threads with small pitches can be produced; such cases are described in this paper. However, thread surface quality after planetary milling is problematic. The technology of initial productive thread milling followed by final thread turning is suggested to obtain metric buttress thread using a new type of millingturning cutters. The results of this investigation can be useful for industrial plants if buttress thread milling on 3-axis CNC machines is necessary.

“…The optimization of the cutter profile is no longer simply adjusting the height of the profile height but iteratively optimizing the feature points of the cutter tooth profile based on the machining error, which greatly improves the optimization efficiency. Lee and Nestler [17] also proposed a new method for thread milling cutter tooth profile optimization from the cutter perspective. The cutter tooth profile feature points in this method are not located in the same plane, but their positions are considered as the function of the feed direction.…”

Thread milling is increasingly used in engineering manufacturing because of its advantages, but there must be error in the thread due to the machining principle.In response to this problem, this paper discussed the causes of thread milling error and established machining error model for the full machining process of thread milling. Firstly, geometric model of thread milling is developed based on the parametric definition of the cutter tooth surface, thread surface and tool -path. Then, based on the cutter motion characteristics of the thread milling penetration -retraction segments and machining segment, the machining error model is established. The calculation of machining error is transformed into solving for the relationship between the position of the intersection of the cutter profile line and the thread profile line generated in the cross section, which means that the three -dimensional problem is transformed into the two-dimensional problem. Finally, the proposed model is proven via thread milling experiments. The simulation results of machining error agree well with the experimental results, which proves the correctness and valid ity of the model. The model provides theoretical support for further research into thread milling machining error.

“…They also proposed an error correction model based on an iterative approach, which changes the radius of the tool trajectory and adapts the mill profile to compensate for the overcut for the symmetrical thread profile with an acceptable error. Lee and Nestler 9 used a simulation-aided design approach to derive the suitable thread profile of the thread mill for both internal and external threads by diminishing the form errors. The introduced method uses iterations to meet the requirements for the desired thread profile.…”

Thread milling is a new machining process as compared to thread tapping. As a thread making process in use for a long time, thread tapping did not have any alternative processes except the thread turning for limited cases until computer numerical control (CNC) technology had enabled the three axes synchronized motion. Therefore, investigations about the thread milling process are less as compared to other machining processes. In this work, the thread profile in the internal thread milling process was derived analytically. Experimental work was also performed to verify the performance of the analytical model. It was revealed that the thread profile produced by the cutting edge of the tool is not a straight line but a curve, and the average slope through the thread profile is less than the slope of the cutting edge of the tool. Besides, the effective thread profile enlarges along the vertical axis and constricts laterally as the ratio of thread mill diameter to thread diameter increases.
