Cutting velocity, Feed rate, cutting depth, tool geometry like its angels, both tool and specimen materials, existence of lubricant.

I am very grateful to you Seyed mohammad Hoseini

Don’t forget target material, such as figuring out the characteristics of the material you will be cutting. Hardness, abrasivness, etc will he needed for those calculations as well. Some materials like Magnesium need to be tightly controlled with speeds to prevent overheating and combustion. You don’t want to use oil on aluminum because sulfur will cause staining and other issues.

I am very grateful to you Wyatt Mustful

The main parameters indicated by Seyed Mohammad Hosseini and the remainings are cutting force, cutting fluid, tool materials, and tool tilt angle(for milling and drilling).

Don't forget the machine capabilities. Max speed, accaleration, accuracy, stiffness, spindle load.

Thank you Dr. Friedhoff

You are welcome. One correction: spindle power instead of spindle load.

I am very grateful to you Dr. Eyob Messele Sefene

One more thing is the entry of the tools. It is also important parameter for cutting different types of surface. it can be ramp or helical,...

I am very grateful to you dear Van Tron Tran

The parameters are revolutions per minute (either the workpiece or the cutting tool) and the corresponding feed of the cutting tool in mm per minute.

First of all, it would be necessary to define the material-tool couple (ex: Tungsten Carbide/Titanium). Then, it would be necessary to choose the cutting conditions allowing to satisfy two main conditions:

- Tool wear/Tool life (according to the Taylor law)

- machine capabilities

*The main cutting conditions are: - Cutting speed Vc (ex for titanium [40-60] m/min)

- Depth of cut Ap

- Feed rate f

Generally, only the three controllable parameters are listed as cutting or process parameters and they are (i) cutting speed, (ii) feed and (iii) depth of cut. There are several other controllable parameters, like the tool geometry, machining environment (i.e. the coolant-lubricant and its application parameters). The choice of the cutting tool is also a controllable parameter.

The cutting forces, specific cutting energy, temperature, nature and extent of tool wear, tool life, surface roughness, tolerance, surface integrity are not controllable parameters. They are rather 'responses' of the machining system.

Flowing from above, there are other parameters that determines the responses of machining systems. These parameters could include cutting tool materials, cutting edge radius, cutting environment and workpiece materials.

These additional parameters are very important to determining the surface finish and aesthetics of machined product.
