What is Groving in lathe machine?
OVERVIEW. Groove cutting on CNC lathes is a multi step machining operation. The term grooving usually applies to a process of forming a narrow cavity of a certain depth, on a cylinder, cone, or a face of the part. The groove shape, or at least a significant part of it, will be in the shape of the cutting tool.
How many types of grooving are there?
There are two types of grooving operations, external and face grooving. In external grooving, a tool moves radially into the side of the workpiece and removes the material along the cutting direction. In face grooving, the tool machines groove in the face of the workpiece.
What is a grooving method?
Grooving or recessing operations, sometimes also called necking operations, are often done on workpiece shoulders to ensure the correct fit for mating parts. When a thread is required to run the full length of the part to a shoulder, a groove is usually machined to allow full travel of the nut.
What is external grooving?
External grooving methods Single cut grooving is the most economical and productive method of producing grooves. However, if the width of the groove is larger than the width of the insert, multiple grooving plunge turning, ramping or profiling can be used to make the groove.
What is shouldering in lathe?
Shoulder Turning: When a workpiece has different diameters and is to be turned, the surface forming steps from one diameter to the other is called the shoulder, and machining this part of the workpiece is called shoulder turning.
What is Partingoff?
Parting off is mainly performed in bar feed machines, often used in mass production. The parting off operation is usually only a small part of the component’s total machining time and therefore not usually seen as a target area for time savings.
What is grooving dance?
The term is often applied to musical performances that make one want to move or dance, and enjoyably “groove” (a word that also has sexual connotations).
Which tool is used in grooving?
Grooving tools are used with lathes to cut channels on the end of a workpiece (face grooving) or into an existing bore (internal grooving). They are used for applications such as creating recesses for retaining rings and necking workpieces to ensure a clean fit when mating parts.
What is step turning?
Definition of step turn : a skiing turn executed in a downhill traverse by lifting the upper ski from the ground, placing it in the desired direction, weighting it, and bringing the other ski parallel.
What is undercut in machining?
In manufacturing, an undercut is a special type of recessed surface that is inaccessible using a straight tool. In turning, it refers to a recess in a diameter generally on the inside diameter of the part. In milling, it refers to a feature which is not visible when the part is viewed from the spindle.
What is filleted shoulder in turning?
Filleted shoulders or corners, are rounded to be used on parts which require additional strength at the shoulder. These shoulders are machined with a round-nose tool bit or a specially formed tool bit (Figure 7-52). This type of shoulder can be turned and formed in the same manner as square shoulders.
What is Cuttingoff operation?
In parting, or cut-off, operations, the objective is to efficiently and securely separate one part of the workpiece from the other. To achieve this, a straight cut is made to a depth that equals the radius of a bar, or workpiece. In grooving operations, the principle is the same but the cut is shallower.
