Things to Know About Turning Process

The turning is a process involved in machining.  It is the process wherein some materials are removed through cutting to manufacture rotational segments.  This procedure will require a machine called the lathe, fixture, workpiece and of course, the cutting tool.  Workpiece is the material that has undergone a pre-shaping method and is attached to the fixture.  The fixture will then be connected to the lathe or the turning machine and will be rotated at a massive high speed.  The tool for cutting (referred as a cutter) will then be secured to the machine.  The cutter will gradually remove the excess parts in the workpiece in order to produce the desired form.  Here are some things that you should know about the entire turning process.

Some Thing You Should Know About Turning Process

The Cycle of the Turning Process

The cycle of the turning process is basically segmented into 4 long processes; loading and unloading of the workpiece, the cutting time, the idle time and the time for replacing the tool.  After these, there may be a requirement for a secondary processing in order to enhance the surface of the workpiece.  The load time corresponds to the length of time needed to introduce the workpiece in the lathe.  This cycle is contingent upon the size, complexity, and weight of the piece.  The cutting time is the length of time required to remove all the excess edges.  Idle time refers to all the time that is non-productive, which may refer to adjusting the workpiece or tool, retracting of the tool or the workpiece and others.  Finally, the tool replacement is incorporated on the worn-out tool life CNC machine.  It is not included in all cycle but after the tool exceeded the expected lifetime.

Cutting Condition

The motion and speed when cutting is highly dependable in different cutting conditions.  Every operation is based on variable cutting condition depending on the tool size, workpiece material and the material of the tool.  There is also a different variation in cutting feed, there are times that the tool is feed into the workpiece and also times that the workpiece is feed into the cutting tool.  Other cutting condition includes the cutting and spindle speed, feed rate and axial and radial depth.

Turning Machines

Turning machineries are commonly referred to as lathes.  They are available in numerous designs and sizes.  Most of the turning machines that you will find in the market are horizontal, but there are also vertical CNC machines that are used for workpiece that has a large diameter.  There are two type of turning machine; the manual and the computerized or the CNC.  Component of this machine includes the turret, compound, cross slide, carriage, tailstock and headstock assembly and the bed.

These are just some of the basic but essential things to know about the turning process.  They are typically incorporated in selling or producing parts to make the entire process more efficient and the parts more affordable.
