“…Swissi et al [18] developed an experimental setup to determine the intrinsic properties of threads and their effect on the tapping process. Ren and Yan [19] used a quasi-static model to predict and simulate the difference in radial pitch diameter during tapping for different chamfer lengths and spindle speeds. Brandão et al [20] reviewed the literature to demonstrate the evolution of the tapping process over the past 20 years but the diameters that are used for forming and machining internal threads range from 3 to 10 mm.…”

Tools with unequal uteless spacing (UFS) feature are used to cut different materials. The UFS tool and a traditional tool differ in terms of the angle between the two cutting edges. The UFS tool experiences smaller axial and radial cutting forces than the traditional tool so cutting vibration is reduced, tool life is increased and the surface roughness of the workpiece increases. This study uses the smaller hole diameter (D), spindle speed (N) and cutting uid concentration (C) for the central composite design (CCD). MINITAB statistical software is used for the second-order response surface modeling of the maximum thread lling rate (f) and the minimum torque (T) for micro-forming M1.2 mm taps using UFS on AL-7075 aluminum alloy. The analysis of variance (ANOVA) results for f and T show that D and C are the important parameters that affect f , and D, N and C signi cantly affect T. Compared with the predicted conditions, the errors in f and T for the experiment are 2.51% and 2.25%, respectively. This study shows that the two second-order mathematical models that are derived using CCD and the response surface method (RSM) feature good prediction accuracy.

“…With the ANOVA results, they concluded that the coefficients of determination ( R 2 ) for f1 and T1 were 97.0% and 90.6%. Ren and Yan, 17 tapping simulation has been realized to reduce the radial pitch diameter difference of the threads. In the study, they developed a quasi-static model to estimate the radial pitch diameter difference in tapping and simulated the radial pitch diameter difference at different chamfer lengths and spindle speeds through this model.…”

Tapping is inherently more complex than other machining processes. The main reason for this complexity is that the chip removal process takes place in a closed environment. For this reason, in order to use the tap tools more efficiently, it is necessary to know the cutting conditions and the stresses that occur in the tool during cutting. In this study, holes of different diameters were drilled in the AISI 1050 material and threaded with M10 taps with three different geometries. Uncoated HSS and TiN coated HSS taps were used in the study. The tapping operations were carried out in dry conditions. The simulation conditions were chosen exactly the same as the experimental conditions. Stresses during tapping were analyzed using the Third Wave AdvantEdge program based on the finite element method (FEM). The tapping tools were modeled by reverse engineering method and then imported in the program. In general, the coating applied to the tools positively affected the stresses on the cutting tool.

A small blind internal thread (SBIT) is used to firmly fasten some functional components to the cover of 3C electronic products. The small internal thread is made in a blind hole using a fluteless forming tap (FFT) that does not produce chips. However, the four geometric parameters (tool width (W), tooth root diameter (D2), front-end diameter (Df) and tooth angle (θ)) for the FFT affect the thread filling rate (f) and the minimum torque (T) for the tapping process. This study reports a Box-Behnken design (BBD) using DEFORM-3D (finite element model) and MINITAB (regression analysis) software to tap 7075-T6 aluminum alloy using a small FFT to achieve a repeatable thread filling rate and minimum torque. The experimental results show that the BBD accurately predicts and simulate the thread filling rate for tapping 7075-T6 aluminum alloy. The modelling software and the experimental design for this study can be used to optimize the design of tools that are used in industrial production.
