In a turning operation on ductile steel, it is desired to obtain an actual surface roughness of 63 µ-in with a 2/64 in nose radius tool. The ideal roughness is given by Eq. (24.1) and an adjustment will have to be made using Figure 24.2 to convert the 63 µ-in actual roughness to an ideal roughness, taking into account the material and cutting speed. Disposable inserts are used at a cost of $1.75 per cutting edge (each insert costs $7.00 and there are four edges per insert). Average time to change each insert = 1.0 min. The workpiece length = 30.0 in and its diameter = 3.5 in. The machine and operator’s rate = $39.00 per hour including applicable overheads. The Taylor tool life equation for this tool and work combination is given by: vT0.23 f 0.55 = 40.75, where T = tool life, min; v = cutting speed, ft/min; and f = feed, in/rev. Solve for (a) the feed in in/rev that will achieve the desired actual finish, (b) cutting speed for minimum cost per piece at the feed determined in (a). Hint: To solve (a) and (b) requires an iterative computational procedure. Use of a spreadsheet calculator is recommended for this iterative procedure

1. A key policy objective of the UK Coalition government, achieved in April 2014, was to raise the personal income tax allowance to £10 000. This has been accompanied by the gradual removal of the same allowance from those earning over £100 000 (see Table 11.3). Evaluate these policies. 2. What would the effects be of cuts in (i) the basic rate of tax; (ii) the top rate of tax? 3. What tax changes (whether up or down) will have a positive incentive effect and also redistribute incomes more equally?

What is accuracy in measurement?

Describe the Danner process.

Elon Savings and Loan Association has a large number of 30-year mortgages with floating interest rates that adjust on an annual basis, and it obtains most of its funds by issuing five-year certificates of deposit. It uses the yield curve to assess the market’s anticipation of future interest rates. Elon believes that expectations of future interest rates are the major force affecting the yield curve. Assume that a downward-sloping yield curve with a steep slope exists. Based on this information, should Elon consider using financial futures as a hedging technique? Explain. (LO2)

How are product variety and production quantity related when comparing typical factories?

Juanita, a Texas resident (5th Circuit), is researching a tax question and finds a 5th Circuit case ruling that is favorable and a 9th Circuit case that is unfavorable.  Which circuit case has more “authoritative weight” and why?  How would your answer change if Juanita were a Kentucky resident (6th Circuit)?

The largest axis of a Cartesian coordinate robot has a total range of 750 mm. It is driven by pulley system capable of a mechanical accuracy = 0.25 mm and repeatability = ±0.15 mm. Determine the minimum number of bits required in the binary register for the axis in the robot's control memory.

Chemical milling is used in an aircraft plant to create pockets in wing sections made of an aluminum alloy. The starting thickness of one workpart of interest is 20 mm. A series of rectangular-shaped pockets 12 mm deep are to be etched with dimensions 200 mm by 400 mm. The corners of each rectangle are radiused to 15 mm. The part is an aluminum alloy and the etchant is NaOH. The penetration rate for this combination is 0.024 mm/min and the etch factor is 1.75. Determine (a) metal removal rate in mm3/min, (b) time required to etch to the specified depth, and (c) required dimensions of the opening in the cut and peel maskant to achieve the desired pocket size on the part.

In a production turning operation, the foreman has decreed that a single pass must be completed on the cylindrical workpiece in 5.0 min. The piece is 400 mm long and 150 mm in diameter. Using a feed = 0.30 mm/rev and a depth of cut = 4.0 mm, what cutting speed must be used to meet this machining time requirement?

A single-point HSS tool with a 3/64 in nose radius is used in a shaping operation on a ductile steel workpart. The cutting speed is 120 ft/min. The feed is 0.014 in/pass and depth of cut is 0.135 in. Determine the surface roughness for this operation.
