Turners are no less essential to the process of picking open a lock (indeed, many of us feel that they are the most essential component of the equation, particularly as far as one’s skill and finesse are concerned), but they will always be designated by that name, or as “turning ...
The convergence criteria for the continuity and momentum equations were set at 1 × 10−4 for residuals, while for the energy equation, the convergence criterion was set at 1 × 10−6. Enhanced wall treatment was implemented for the wall boundary conditions, and the realizable k-ε ...

For a mass moving in a vertical circle, draw a free body diagram for when the mass is at the highest point of its path, and then write the force summation equation for that free body diagram. A 70kg stunt driver rounds a...
The manner by which the tool offset δx enters this equation is different from the tool offset δy. A binomial expansion of Equation 2 can be derived by assuming that the rotational coordinate is much larger than the tool offsets. This hypothesis is correct over a major part of the surface...
The equation of S/N ratio is defined as:(1)SN=-10×log1n∑i=1nyi2Where, S/N is the ratio for lower the better, yi is the result of the characteristics and n is the number of repetitions in a trial. Table 3. Cutting parameter with levels. No.Parameters Empty CellLevel Empty Cell...
Then the cutting torque can be calculated by solving a 2 nd order difference equation at a given cutting condition. A graphical programming method is used to implement the torque monitoring system developed in this study to the computer and at the same time monitor the torque of the spindle ...
