Introduction General part

Calculation of the section area.
The main area of the section is determined by the category of equipment and overall dimensions. We have 6 benches on our site.
Of these, large benches3 x30 = 90 m and small benches 3x20 = 60 m .
_Overall: Q =150 m
The area of ancillary rooms is allocated at the expense of 25-30% of the main area.
Q =150 X 0.25=37,5 m .
The outside area is assumed to be equal to 10% of the working area
Q =15m
The area for household services is 20-30% of the main area
Q =150x0.22=33 m .
_{Total area of the section:} Q =150+37,5+15+33=235,5 m

Figure 4.1. Workshop loading schedule.
The main indicator that determines the effectiveness of technological processes in the design of workshops is the cost of production.
An additional non-standard device for the operation of any technological process is required to determine the costs incurred in order to determine the technological cost of the operation using the device mechanism. To do this, you need to know the following basic information.
1. Annual production program;
N = 90,000 pieces
2. The amount of labor expended on the operation performed (per unit)
or unit-calculation time), t = 1.609 min
3. Used machine model; horizontal milling machine 6R80G
4. Price by price list; K = 1230000 soums
5. Load factor; K = 0.33
6. Basic time utilization factor; K = 0.22
7.Work category for a given operation; 3
8. Hourly rate for a certain category; C = 1220 soums / hour
The stated costs incurred for the performance of a given technological operation are determined by the following formula;
Device: Z =S +E K =134,8+0,15·25,2=138,5 soums
Without device: Z =S +E K =134,2+0,15 ·25,2=137,9 soums
Here: Z-Quoted costs incurred for detail operation. UZS
C- Technological cost of the given operation UZS;
E - Capital investments, normative efficiency coefficient Ye = 0.15
K - Relative capital investment per transaction, UZS
Determined with the following formula.
K =K/N=757680/50000=25,2 soums
In this case, the capital investment in the K-given option, UZS
Annual production program; N=90000 units.
Capital expenditures mainly include equipment costs.
Estimates do not take into account the relatively small cost of production sites.The cost of transporting and assembling the machine is taken as 10% of its value. In the case of multi-series production, each machine can perform several different operations. Therefore, when determining the capital investment for a detailed operation, it is necessary to determine the employment coefficient with the given operation of the machine. This coefficient depends on the load factor K of the machine with this operation. If μ = 0.851, the coefficient is K <0.85, if K = 0.85, the machine is additionally loaded with other details and m is determined as follows:
μ= K /K =0,45/0,8=0,56
Here: K - normative load factor; K =0.8
Determining the cost of the machine on the recalculator as K , and determining the cost of its transportation and installation at 10%, the capital investment for a given detail operation is determined as follows.
K=1,1 μ K = 1,1·0,56·1230000=757680 soums.
The technological cost of the operation C is calculated using the following formula:
C =t /60(C +H )=(1.609/60)(2196+42,3)=134,2 soums
Here: t -piece-calculation time. Min
C - the salary of the machine worker for one hour of work, UZS
H - cost of the machine per hour, UZS
The salary of a machine worker is determined from the following formula.
C =1.8C =1,8·1220=2196 soums
Here: C - hourly rate for this category of workers, soums (Table 4)
1.8 Additional payments and coefficient taking into account social insurance (40%, premiums, 40% social insurance contributions).
The cost per hour of machine work is determined from the following empirical formula;
H =s10 xK =1,65·0,001·757680 42,3 soums
Here; s-coefficient taking into account the nature of production and machine operating costs; K- capital investment in a given machine, UZS.
S = 1.65, taking into account the operating costs of the machine and equipment in serial production;
If the calculations do not take into account the costs incurred for the operation of the device a = 1.22.
When calculating the technological cost of a variant of the machine equipped with additional devices, special equipment or devices, the cost of this device or device per 1 hour of work is taken into account, which is determined by the following formula:
H =0,18∙10 =0,18·0,001·55000=9,9 soums
Here; C - costs for the manufacture of the device or device, UZS (Table 6).
In this case, the technological cost of the operation is determined as follows;
C =t /60(C +H +H )=(1.609/60)(2196+42,3+9,9)=134,8 so’m
