How should the Part Cost Calculation be on the CNC Vertical Machining Center Machine?
The cost of a part produced on a CNC (Computer Numerical Control) Vertical Machining Center (VMC) machine is typically calculated using a combination of direct and indirect costs, similar to CNC lathe.
- Direct costs: These are the costs that are directly associated with producing the part, such as the cost of the raw material, the cost of the cutting tools, and the cost of the electricity used to run the machine.
- Indirect costs: These are the costs that are not directly associated with producing the part, but are still necessary to produce the part, such as the cost of machine maintenance and repair, the cost of quality control, and the cost of overhead (rent, taxes, etc).
To calculate the cost of a part, direct costs are added together and then indirect costs are added on top of that. The total cost of the part is then divided by the number of parts produced to get the cost per part.
A good cost calculation should also take into account the cost of scrap, which is the cost of the material used for parts that are not suitable for use. The scrap rate should be monitored and reduced as much as possible to keep the cost of the part low.
It is also important to consider the setup time, which is the time required to set up the machine for a specific part. The setup time should be minimized as much as possible to increase efficiency and reduce the overall cost of the part. Additionally, the run time should be considered, which is the time required for the machining process of the part.
In VMC machines, the cost of the pallet system should also be considered as it is an important component of the machine, and its use can greatly increase the efficiency and productivity of the machine.
Overall, the cost calculation for a part produced on a CNC VMC machine should take into account both direct and indirect costs, as well as the cost of scrap, setup time, run time, and other relevant factors. This will help to ensure that the cost of the part is as low as possible while still maintaining the required quality and efficiency.
