Fundamentals of Machining

Process of removing unwanted material from a workpiece in the form of chips. If the workpiece is metal, the process is often called metal cutting of metal removal.

• Machining

• Reconditioning

• Tooling

• Shaping

Which basic machining process represents the following image:

• Turning

• Milling

• Grinding

• Drilling

Which basic machining process represents the following image:

• Turning

• Milling

• Grinding

• Drilling

Coated high-speed steel (HSS) and uncoated and coated carbides are currently the most extensively used tool materials.

• true

• false

Defined by ease or difficulty with which the metal can be machined

The following are inputs in metal cutting process, except:

• Surface finish

• Cutting tool parameters

• Machine tool selection

• Workpiece parameters

Acts primarily as a coolant and secondly as a lubricant, reducing the friction effects at the tool/chip interface and the work flank regions.

Is the amount of material removed per revolution or per pass of the tool over the workpiece. Units can be inches per revolution, inches per cycle, inches per tooth.

• Depth of cut (DOC)

• Feed (fr)

• Speed (V)
