The same grade of cemented carbide tooling is available in two forms for turning operations in the machine shop: disposable inserts and brazed inserts. Feed = 0.30 mm/rev. The Taylor equation parameters for this grade are n = 0.25 and C = 300 (m/min). For the disposable inserts, the price of each insert = $6.00, there are four cutting edges per insert, and the average tool change time = 1.0 min. Forthe brazed insert, the price of the tool = $30.00, and it can be used a total of 15 times before it must be scrapped. The tool change time forthe regrindable tooling = 3.0min. The standardtime to grind orregrind the cutting edge is 5.0min, and the cost rate to grind = $20.00/hr. Machine time on the lathe costs $24.00/hr. The work part to be used in the comparison is 375 mm long and 62.5 mm in diameter, and it takes 2.0 min to load and unload the work. For the two cases, compare the: a. cutting speedsfor minimum cost b. tool lives c. cycle times and costs per unit of production. d. Which tool would you recommend?

Suppose the real risk-free rate and inflation rate are expected to remain at their current levels throughout the foreseeable future. consider all factors that affect the yield curve. then identify which of the following shapes that the u.s. treasury yield curve can take. check all that apply.

Analyzing and computing accrued warranty liability and expense waymire company sells a motor that carries a 60-day unconditional warranty against product failure. from prior years' experience, waymire estimates that 2% of units sold each period will require repair at an average cost of $100 per unit. during the current period, waymire sold 69,000 units and repaired 1,000 units. (a) how much warranty expense must waymire report in its current period income statement? (b) what warranty liability related to current period sales will waymire report on its current period-end balance sheet? (hint: remember that some units were repaired in the current period.) (c) what analysis issues must we consider with respect to reported warranty liabilities?
