Calculating machining costs for CNC machines can seem complicated. However, by breaking down the process into simple steps, it becomes much easier. In this article, we will explore how to calculate machining costs for CNC machines. We will look at the factors involved, and the steps to follow, and provide examples to help you understand the process. Let’s get started!
Understanding CNC Machining Costs
Before we jump into the estimation, it’s essential to comprehend the various variables that add to CNC machining costs. Here are the fundamental elements:
- Material Cost: The expense of the natural substance used for machining.
- Machine Cost: The expense of working the CNC machine, including deterioration, support, and energy utilization.
- Work Cost: The expense of the work expected to work the machine and handle the workpieces.
- Tooling Cost: The expense of the apparatuses used in the machining system, including wear and substitution.
- Above Cost: Extra costs like lease, utilities, and authoritative costs.
How to calculate machining cost for CNC machines Step-by-Step process
Presently, we should go through the moves toward ascertaining machining costs for CNC machines.
Decide Material Cost
Material costs are the expense of the natural substance used for machining. To ascertain material cost:
- Measure the Material Volume: Decide the volume of the unrefined substance required for the part.
- Track down the Material Thickness: Look into the thickness of the material being used.
- Ascertain Material Weight: Duplicate the volume by the thickness to get the heaviness of the material.
- Decide Material Value: Find the expense per unit weight of the material.
- Ascertain Material Expense: Duplicate the material load by the expense per unit weight.
For instance, on the off chance that you want to machine a section from aluminum:
- Volume: 100 cubic centimeters (cm³)
- Density of Aluminum: 2.7 grams per cubic centimeter (g/cm³)
- Weight: 100 cm³ × 2.7 g/cm³ = 270 grams
- Cost per Kilogram of Aluminum: $3
- Material Cost: 0.27 kg × $3/kg = $0.81
Calculate Machine Cost
Machine costs incorporate the expense of working the CNC machine. To work out machine costs:
- Decide Machine Rate: Track down the hourly rate for working the CNC machine. This rate incorporates devaluation, upkeep, and energy costs.
- Gauge Machining Time: Decide how long it will require to machine the part.
- Calculate Machine Cost: Duplicate the machining time by the machine rate.
For instance, on the off chance that the machine rate is $50 each hour and the machining time is 2 hours:
Machine Cost: 2 hours × $50/hour = $100
Calculate Work Cost
Work costs are the expense of the work expected to work the CNC machine and handle the workpieces. To work out work costs:
- Decide Work Rate: Track down the time-based compensation of the machine administrator.
- Gauge Work Time: Decide how long the administrator will spend at work.
- Work out Work Cost: Increase the work time by the work rate.
For instance, assuming the work rate is $20 each hour and the work time is 2 hours:
Work Cost: 2 hours × $20/hour = $40
Calculate Tooling Costs
Tooling costs are the expense of the devices used in the machining system. To ascertain tooling costs:
- Decide Apparatus Cost: Find the expense of the instruments required for the gig.
- Gauge Apparatus Life: Decide the number of parts that can be machined before the device should be supplanted.
- Ascertain Tooling Cost per Part: Gap the device cost by the instrument life to get the expense per part.
For instance, on the off chance that the device cost is $100 and it can machine 200 sections:
Tooling Cost per Part: $100 ÷ 200 sections = $0.50 per part
Calculate Above Cost
The above costs are extra costs like leases, utilities, and regulatory costs. To work out the above costs:
- Decide Above Rate: Find the above rate as a level of the complete machining cost.
- Work out the Above Cost: Duplicate the all-out machining cost by the above rate.
For instance, assuming that the above rate is 10% and the all-out machining cost is $100:
Above Cost: $100 × 10% = $10
Calculate Absolute Machining Cost
At last, include every one of the cost to get the absolute machining cost:
- Material Expense: $0.81
- Machine Cost: $100
- Work Cost: $40
- Tooling Cost: $0.50
- Above Cost: $10
- Absolute Machining Cost: $0.81 + $100 + $40 + $0.50 + $10 = $151.31
Example Calculation
How about we go through a model estimation bit by bit? Assume we want to machine a section from steel.
- Material: Steel
- Volume: 200 cubic centimeters (cm³)
- The thickness of Steel: 7.85 grams per cubic centimeter (g/cm³)
- Weight: 200 cm³ × 7.85 g/cm³ = 1570 grams = 1.57 kg
- Cost per Kilogram of Steel: $2
- Material Expense: 1.57 kg × $2/kg = $3.14
- Machine Rate: $60 each hour
- Machining Time: 3 hours
- Machine Cost: 3 hours × $60/hour = $180
- Work Rate: $25 each hour
- Work Time: 3 hours
- Work Cost: 3 hours × $25/hour = $75
- Apparatus Cost: $120
- Instrument Life: 300 sections
- Tooling Cost per Part: $120 ÷ 300 sections = $0.40 per part
- Above Rate: 15%
- Absolute Machining Cost: $3.14 + $180 + $75 + $0.40 = $258.54
- Above Cost: $258.54 × 15% = $38.78
- Absolute Machining Cost: $258.54 + $38.78 = $297.32
