Manufacturing Cost = Variable costs + Factory Expenses +
General and Administrative Expenses
= $3,280,000 + $300,000 + $310,000
=
$3,890,000
Sales, staff, salaries and commissions: $100,000
Total Cost = Manufacturing costs + Sales, staff, salaries and commissions
= $3,990,000
Manufacturing cost for a turbine = $3,990,000
Profit Margin = Profit / Sales
0.15 = Profit / Sales -> equation 1
Sales = Profit + Total Cost
Sales = (0.15)Sales + $3 990 000 -> equation 2
Interception equation 1 & 2
Sales = $ 4 987 500.00
Sales = Selling Price
Profit Margin = Profit / Sales
0.15 = Profit / Sales -> equation 1
Sales = Profit + Total Cost
Sales = (0.15)Sales + $3 990 000 -> equation 2
Interception equation 1 & 2
Sales = $ 4 987 500.00
Sales = Selling Price
Total Annual Sales = 60 units
Selling Price for One Turbine = Selling Price / 60 = $4,987,500.00
/ 60
Selling Price = $83,125.00 per unit
Selling Price = $83,125.00 per unit
ASSIGNMENT 17.3 BREAK-EVEN POINT
QUESTION
The type of tooling to make for a manufacturing process depends on the
expected total quantity of parts. Tooling made from standard components and
less wear-resistant materials (soft tooling) can be made more quickly and
cheaply than conventional tooling made from hardened steel (hard tooling). Use
the concept of break-even point to determine the production quantity for which
soft tooling can be justified.
The following cost data applies:
Soft tooling Hard
tooling
Tool Tooling cost
CS $600
CH $7500
Setu Setup cost
SS $100
SH $60
Unit Unit Part cost
CPS $3.40
CPH $0.80
ANSWER
The break-even point is the sales or production volume at which sales
and costs balance.
CH + (QBEP/b) SH +
CPH QBEP = CS + (QBEP/b) SS+ CPS QBEP
Break-even point,
QBEP = CH - CS /
[(SS - SH}/b) + (CPS - CPH)]
= 7500 – 600/ [((100 – 60)/500) + (3.4
– 0.8)]
= 2574.63
= 2575 unitsAssigment Chapter 17
Problem 17.2
QUESTION:
Many consumers item today are designed in the United State
and manufactured over-seas where labor cost is much lower. A middle range
athletic shoe from a name brand manufacturer sells for $70 in the U.S. The shoe
company buys the shoe from an off-shore supplier for $20 and sells to the
retailer for $36. The profit margin for each unit in the chain is: supplier-9%,
shoe company-17%, retailer-13%. Estimate major categories of cost breakdown for
each unit of chain. Do this as a team problem and compare the results for the
entire class.

ASSIGNMENT 17.1
QUESTION:
In an environmental upgrade of a minimill making steel bar, it is found
that a purchase must be made for a large cyclone dust collector. It is the time
of the year for capital budget submissions, so there is no time for quotations
from suppliers. The last unit of that type was purchased in 1985 for $35,000.
It had a 100ft3/min capacity. The new installation in 2012 will
require 1000ft3/min capacity. The cost escalation for this kind of
equipment has been about 5 percent per year. For budget purposes, estimate what
it will cost to purchase the dust collector.
Answer:
C1 = C0 (L1/L0)x (Cost-Size Relationship ~page799)
- C0= $35,000
- L0= 100ft3/min
- L1= 1000ft3/min
- C1= ?
Based on Table 17.4 in the text book, x for dust collector= 0.61. Because of
economies of scale, the new unit has 10 times the capacity as the unit
purchased in 1985 will not cost 10 times more. However, the purchase cost will have increased because of inflation in
the 27 years since it was purchased in 1985. Assuming cost inflation in of 5%
per year, the original cost of $35,000 is now equivalent to:
P= F(1+i)n
P=35000(1+0.05)27
= 35000(2.92526)
= $130 671.00
P= F(1+i)n
P=35000(1+0.05)27
= 35000(2.92526)
= $130 671.00
Thus, the cost estimation can be calculated as:
C1 = C0 (L1/L0)x =130 671.00(1000/100)0.61
= $ 532 327.00
ASSIGNMENT 13.1 SHAPE-REPLICATION AND SHAPE-GENERATIVE
ASSIGNMENT 13.1
QUESTION :
Classify the following manufacturing processes as to whether they
are shape-replication or shape-generative:
(a)Honing the bore of a cylinder,
(b)Powder metallurgy gear,
(c)Rough turning a cast roll,
(d)Extrusion of vinyl house
siding.
ANSWER:
Shape replication is an example of process under mass conserving which the part replicates the information stored in the tooling by being forced to assume the shape of the surface of the tool cavity. The examples of shape-replication process can be define by the process of casting, injection molding, and closed-die forging. In addition, during mass reducing processes or shape-generation processes, the starting material is greater than the mass of the final part. This is because the part shape is produced by the relative motion between the tool and the workpiece. The examples manufacturing processes that undergo through this process is milling and drilling.
The manufacturing processes are classified as follow:
(a)
Honing the bore of a cylinder
(b)
Powder metallurgy gear
(c)
Rough turning a cast roll
(d)
Extrusion of vinyl house siding
