The following operations are each defined by the type of cutter used and the path of that cutter to remove material from the workpiece. These are cylindrical multi-point cutting tools that have sharp teeth spaced around the exterior. Please help improve this article by adding citations to reliable sources. Turning machines can also be classified by the type of control that is offered. Counter boring is needed for receiving the head of a socket head cap screw. Most defects in turning are inaccuracies in a feature's dimensions or surface roughness.
Groove cutting on CNC lathes is a multi step machining operation. Grooving tools are also used for a variety of special machining operations. Grooving tool is usually a carbide insert mounted in a special tool holder, similar to any other tool.
Grooving and threading are single-point machining operations performed on lathes, When the machine spindle rotates in a counter-clockwise direction. The ability to efficiently cut off work-pieces and blanks in lathes has always been.
Lathe Operations | Grooving. October 21, By admin. Grooving: Grooving is the act of making grooves of reduced diameter in the workpiece. clip_image
CNC lathes rotate the workpiece and move the cutting tool based on commands that are preprogrammed and offer very high precision.
Workpiece Select a material that minimizes overall cost. The threads can be cut to a specified length and pitch and may require multiple passes to be formed. The tooling cost for machining is determined by the total number of cutting tools required and the unit price for each tool. The scrap material, in the form of small material chips cut from the workpiece, is propelled away from the workpiece by the motion of the cutting tool and the spraying of lubricant.
Operations During the process cycle, a variety of operations may be performed to the workpiece to yield the desired part shape. As the recess is usually narrow, the cutting edge is kept narrow.

|In some operations the tool feeds into the workpiece and in others the workpiece feeds into the tool. Disclaimer: All process specifications reflect the approximate range of a process's capabilities and should be viewed only as a guide.
Before the operation starts, the carriage is locked in position on the lathe bed and the cutting tool is held rigidly on the tool post with the compound slide set parallel to the lathe axis. Chamfering is an essential operation before thread cutting so that the nut may pass freely on the threaded work piece. This operation will be taught in detail in further classes.

Lathe Operations - Grooving and Tread Relieving. Grooving or thread relieving is often done at the end of a thread to allow for the full travel of the thread to a shoulder. Tools can be Mount the workpiece in the machine. Set the parting tool on. When applying a grooving insert in a turning operation, a controlled degree. face grooves and any other feature you can machine on a lathe.
Cutting parameters In turning, the speed and motion of the cutting tool is specified through several parameters.
Eccentric Turning. Therefore, a feature is typically machined in several passes as the tool moves to the specified axial depth of cut for each pass.
In some areas they may be known as turnings. Return to top. The cutter is typically a single-point cutting tool that is also secured in the machine, although some operations make use of multi-point tools.
Grooving operation on lathe machine
|A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action.
As with the carriage, the cross slide is powered by a motor or hand wheel. Also, any cost attributed to cutting the workpieces from the stock also contributes to the total material cost.

There are three principal forces during a turning process:. A large radial depth of cut will require a low feed rate, or else it will result in a high load on the tool and reduce the tool life. For a multi-point tool, the cutting feed is also equal to the feed per tooth, measured in inches per tooth IPTmultiplied by the number of teeth on the cutting tool.
Cutting feed - The distance that the cutting tool or workpiece advances during one revolution of the spindle, measured in inches per revolution IPR.
Knurling. Process if impressing a diamond-shaped or straight-line patter into the surface of the workpiece.

Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes Turning operations are carried out on a lathe machine which can be manually or CNC operated. Grooving can be performed on internal and external surfaces, as well as on the face of the part (face grooving or trepanning).
Facing - A single-point turning tool moves radially, along the end of the workpiece, removing a thin layer of material to provide a smooth flat surface.
Tapping - A tap enters the workpiece axially through the end and cuts internal threads into an existing hole. These single point cutting tools are available in a variety of shapes that allow for the formation of different features.
Turning Process, Defects, Equipment
Reaming removes a minimal amount of material and is often performed after drilling to obtain both a more accurate diameter and a smoother internal finish. The carriage rests on tracks that lay on the bed, called "ways", and is advanced by a lead screw powered by a motor or hand wheel. It is similar to the drilling process - the reamer is held in the tailstock to carry out the reaming operation. Before the operation starts, the carriage is locked in position on the lathe bed and the cutting tool is held rigidly on the tool post with the compound slide set parallel to the lathe axis.
