The role of the functional diameter is very important to the thread fitting property; however, the main feature of the thread is the spiral surface in space, which has many parameters and is difficult to measure. To obtain a thread functional diameter more in line with the definition of the standard, an approach based on a compliant mechanism theory is presented for the design of a synthetic measurement probe, and a multi-degree of freedom (DOF) movement of the sensitive probing element is realized. High stiffness and high flexibility of the probe are achieved in the undesired direction and direction of freedom, respectively. A method in which the error source is analyzed is adopted to evaluate the measurement uncertainty. The expanded uncertainty of the thread functional diameter measurement is 0.008 mm (k = 2), which is due to the probe mechanism error motions.

<p>Virtual Reality is a computer-generated, mock environment that can allow people to interact with it in a seemingly real way by using certain types of specialized equipment. It is mainly used for training or educational purposes and allows for “real-life” training in a safe and monitored environment. Virtual training can be used in many different fields such as medical, military, biomedical research, aviation, and many others. However, this paper reviews the most cited publications related to the application of virtual reality for training in the United States Military. As a result, researchers can find research venues based on the challenges, risk, and infrastructures.</p>

“…Three-dimensional (3D) coordinate measurement is widely used in industrial production and scientific research, such as quality inspection of work piece, surface reconstruction from point clouds and measurement of geometric error of machine tools. [1][2][3] The coordinate measuring machine (CMM) is one of the most typical instruments for 3D coordinate measurement, and it is of high measuring accuracy. But, its measuring volume is restricted by the measuring range, and the samples to be measured must be fixed on the table of the CMM, so CMM is not suitable for geometric error measurement of machine tool and large-scale metrology.…”

This article proposes a modified sequential multilateration method for measuring three-dimensional coordinates. The measuring system consists of a single laser tracker and four relay targets whose relative positions have been pre-calibrated by the multilateration method. The laser tracker is fixed on three prescribed positions successively, and these positions can be calibrated by using the distances between the laser tracker and the four relay targets based on the multilateration principle. Subsequently, the three-dimensional coordinates of each under-test point can be determined by the three laser trackers’ positions based on the trilateration principle. This method is more flexible than previous multilateration methods for three-dimensional coordinate collection, especially if the measurement space is partially covered by other objects. The mathematical model of this method is established. Based on the Monte Carlo method, a series of computer simulations are performed to optimize the system arrangement by investigating the performances of the measuring system with different system arrangement, and an optimal system arrangement is finally obtained. Practical measurement is also conducted to demonstrate the validity of the proposed method by comparing with a reference coordinate measuring machine.
