10 Turning Operations You Need To Know

turn_op-10.png

Lathe machines create sophisticated parts for medical, military, electronics, automotive, and aerospace applications. Read on to find out the top 10 machining operations performed on a lathe. 

A lathe is capable of performing numerous machining operations to deliver parts with the desired features. Turning is a popular name for machining on a lathe. Nevertheless, turning is just one kind of lathe operation.

The variation of tool ends and a kinematic relation between the tool and workpiece results in different operations on a lathe. The most common lathe operations are turning, facing, grooving, parting, threading, drilling, boring, knurling, and tapping.  

1. Turning

Turning is the most common lathe machining operation. During the turning process, a cutting tool removes material from the outer diameter of a rotating workpiece. The main objective of turning is to reduce the workpiece diameter to the desired dimension. There are two types of turning operations, rough and finish. 

Rough turning operation aims to machine a piece to within a predefined thickness, by removing the maximum amount of material in the shortest possible time, disregarding the accuracy and surface finish. Finish turning produces a smooth surface finish and the workpiece with final accurate dimensions.

Different sections of the turned parts may have different outer dimensions. The transition between the surfaces with two different diameters can have several topological features, namely step, taper, chamfer, and contour. To produce these features, multiple passes at a small radial depth of cut may be necessary.

step.png

Step Turning

Step turning creates two surfaces with an abrupt change in diameters between them. The final feature resembles a step.


taper.png

Taper Turning

Taper turning produces a ramp transition between the two surfaces with different diameters due to the angled motion between the workpiece and a cutting tool.


cham.png

Chamfer Turning

Similar to the step turning, chamfer turning creates angled transition of an otherwise square edge between two surfaces with different turned diameters.


cont.png

Contour Turning

In contour turning operation, the cutting tool axially follows the path with a predefined geometry. Multiple passes of a contouring tool are necessary to create desired contours in the workpiece. However, form tools can produce the same contour shape is a single pass.


2. Facing

facing.png

During the machining, the length of the workpieces is slightly longer than the final part should be. Facing is an operation of machining the end of a workpiece that is perpendicular to the rotating axis. During the facing, the tool moves along the radius of the workpiece to produce the desired part length and a smooth face surface by removing a thin layer of material.

 

3. Grooving

groov.png

Grooving is a turning operation that creates a narrow cut, a "groove" in the workpiece. The size of the cut depends on the width of a cutting tool. Multiple tool passes are necessary to machine wider grooves. 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. 

4. Parting 

part.png

Parting is a machining operation that results in a part cut-off at the end of the machining cycle. The process uses a tool with a specific shape to enter the workpiece perpendicular to the rotating axis and make a progressive cut while the workpiece rotates. After the edge of the cutting tool reaches the centre of the workpiece, the workpiece drops off. A part catcher is often used to catch the removed part. 

5. Threading

thread.png

Threading is a turning operation in which a tool moves along the side of the workpiece, cutting threads in the outer surface. A thread is a uniform helical groove of specified length and pitch. Deeper threads need multiple passes of a tool.

6. Knurling

Knurling operation produces serrated patterns on the surface of a part. Knurling increases the gripping friction and the visual outlook of the machined part. This machining process utilizes a unique tool that consists of a single or multiple cylindrical wheels (knurls) which can rotate inside the tool holders. The knurls contain teeth that are rolled against the surface of the workpiece to form serrated patterns. The most common knurling pastern is a diamond pattern.

7. Drilling

Drilling operation removes the material from the inside of a workpiece. The result of drilling is a hole with a diameter equal to the size of the utilized drill bit. Drill bits are usually positioned either on a tailstock or a lathe tool holder.

8. Reaming

ream.png

Reaming is a sizing operation that enlarges the hole in the workpiece. In reaming operations, reamer enters the workpiece axially through the end and expands an existing hole to the diameter of the tool. 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.

boring.png

9. Boring

In boring operation, a tool enters the workpiece axially and removes material along the internal surface to either create different shapes or to enlarge an existing hole.

tap.png

10. Tapping

Tapping is the process in which a tapping tool enters the workpiece axially and cuts the threads into an existing hole. The hole matches a corresponding bit size that can accommodate the desired tapping tool. Tapping is also the operation used to make a thread on nuts.


Conclusion

Lathes are capable of machining pieces with sophisticated features. The final part features are produced by the utilization of various tools and by changing the kinematical relationship between the cutter and a workpiece. In this article, we explained ten different lathe operations. 

We at Turntech Precision provide the top quality parts machined on the Swiss-type lathes utilizing turning, facing, grooving, threading, knurling, boring, and tapping operations. We work closely with our customers to provide them with the best solution to their engineering problems in a variety of industries. Contact us today with your inquiries.

Chip off the old block: How to control the chaos that is “chip formation”

chip-10.png

With the advent of advanced factory automation and Industry 4.0, the autonomous manufacturing systems are gaining in importance. Proper chip disposal is an essential enabler of truly autonomous machining. Read on to find out about factors affecting chip formation and techniques for their control.

In recent decades machine tools kept on continuously improving, and the autonomous machining systems established themselves as irreplaceable components of factory automation. The machining process problems, such as chip disposal, stand in the way of efficient autonomous machining systems. Therefore, effective chip control is a crucial feature of all modern machining systems.

The characteristics of formed chips depend on the type of machining material, ductile or brittle. On the other hand, machining process parameters also play an important role in the chip formation, namely, feed rate, rake angle, cutting speed, depth of cut, and friction forces (use of lubricants and coolants).

Machine operators generally tune the process parameters to obtain high-quality parts and efficient machine operation, while relaying on the chip breakers to help them with chip disposal.   


Formation of Chips

During the machining, as the tool advances into the workpiece, the metal in front of it compresses. When compression exceeds the compression limit, the metal separates from the workpiece and flows plastically in the form of a chip (shear deformation).

tec_turning_chip_control_01_en.png

The flow of metal happens at the shear plane due to the primary shear. The shear plane extends at an angle upwards from the uncut surface in front of the tool. The value of the shear angle depends on the type of material and the cutting conditions (tool angle, cutting speed, etc.). When the shear angle is small, the path of shear will be long, chips will be thick, and the cutting force will be high, and vice versa. 

As the chip slides along the face of the tooltip, the secondary shear occurs due to the friction. The friction increases the temperature of the machining process, causing the chips to heat up excessively. 


Types of Chips

The types of chips formed during the machining of metals are;

  • Segmented chips

  • Continuous chips

  • Continuous chips with the built-up edge (BUE)

Segmented (Discontinuous) Chips

Segmented chips usually occur when machining brittle metals such as brass, bronze, or cast iron. In general, the segmented chips are the result of the following machining conditions;

  • Low feed rate;

  • Low rake angle;

  • High cutting speed;

  • High tool-chip friction;

  • Significant depth of cut.

The segmented chips provide clean surface finish in brittle metals, easy chip disposal, longer tool life, and reduced power consumption. In the case of ductile metals, the segmented chips usually result in poor surface finish and lower tool life.

Continuous Chips

Continous chips usually occur during the machining of malleable metals such as steel, copper, or aluminium at high cutting speeds. During the machining, the temperature between the tooltip and ductile workpiece gets high. Each layer of the removed metal gets welded to the previous layer, forming a long and continuous chip stream. In general, the continuous chips occur under the following machining conditions;

  • Small depth of cut;

  • Large rake angle;

  • High cutting speed;

  • Low tool-chip friction (use of lubricants or coolants);

  • Sharp cutting edge.

The continuous chips provide clean surface finish, longer tool life, and reduced power consumption. On the other hand, the disposal of this type of chips is challenging. It is necessary to use chip breakers to improve disposal conditions.  

Continuous Chips With the Built-Up Edge (BUE)

Different-chip-formation-mechanisms-generated-from-PM2000-specimen-machined-at-same_Q640.jpg

The formation of continuous chips with the BUE is caused by high friction between the tool and the chip while machining ductile metals. Under these conditions, some chip particles tend to bond to the tooltip. As bonded material forms the new cutting edge, it continues to build up until it breaks off from the tooltip. During the breakoff, the built-up material bonds both to the chip and the workpiece surface, resulting in poor surface finish. A different name for the formation of BUE is "chip welding." In general, continuous chips with BUE occur under the following conditions:

  • Low rake angle;

  • Low cutting speed;

  • High friction forces;

  • High feed.

Since continuous chips with BUE poorly affect the tool life, increase the power consumption, and cause the poor surface finish, their prevention is crucial. Measures such as reducing friction through the use of lubricants, preventing metal-to-metal contact through tool coatings, and reducing the temperature through the use of coolants, have a positive effect on the prevention of chip welding. 


Chip Control

Features of a Turning Insert

Features of a Turning Insert

Machining of malleable metals such as steel at high cutting speed and large rake angles leads to the formation of long and stringy chips. These sharp-edged, hot, and continuous chips that come out at high speed can endanger the safety of machine operators, damage the product by entangling with the tool and make their disposal complicated. It is imperative to break chips into manageable geometry.

Chips can break off either by self-breaking or by forced breaking. When machining ductile materials, due to the temperature and flow velocity difference, the chips tend to curl. The curled chips can self-break in three different ways:

  • By natural fracturing due to the cooling-induced strain;

  • By striking against the workpiece;

  • By striking against the tool.

The most common method for forced breaking is the use of a chip breaker.

Chip Breakers

Chipbreaker of insert with different coating and substrate

Chipbreaker of insert with different coating and substrate

The most basic function of chip breakers is to force chips to curl more tightly than they naturally would. Forced curling causes the chip to break off by striking either against the workpiece or the tool. Chip breakers improve machining efficiency by enhancing chip control and reducing cutting forces.

Most modern chip breakers come in the form of grooves or obstructions on the cutting tool. The design of chip breakers revolves around finding the best geometry for a given machining scenario, which will create the stress in the chip and cause it to break off easily.

Groove type chip breakers incorporate a small groove behind the leading cutting edge. The geometry of the curve determines the radius of the chip curvature.

Obstruction type chip breaker features distinctive geometry that resembles a step. The obstruction can be either integral or attached to the cutting tool. In the case of the "attached" type, it is possible to adjust them for various machining conditions.


Conclusion

The machining process is a subtle interplay of physics, material science, and mechatronics. During the machining, material removal is a result of interaction forces between the workpiece and the machining tool. The nature of these interaction forces defines the colour and the size of chips. The chips are valuable research and diagnostic data for cutting engineers. Nevertheless, when not handled properly, chips tend to decrease the productivity of machines.

P1120792.jpg

Three distinctive types of chips can occur during the machining, segmented, continuous, and continuous with BUE. The formation of chips depends on the material selection and machining process parameters.

Chip disposal is a vital factor to consider when improving overall machining efficiency and planning for the autonomous operation of the machines. Even though the segmented chips and continuous chips are self-breaking under certain machining conditions, it is a rule of thumb to use chip breakers in machining setups.

Breaking of the chips into suitable lengths by a chip breaker prevents the chip entanglement with the tool, decreases the vibration, and prevents the tool damage. Chip breaker also reduces the cutting resistance, which in turn prevents chipping and fracturing of the cutting edge. 

When using a chip breaker, it is necessary to choose the right one for the job. For turning operations such as finishing, medium, and roughing, we have to choose correct chip breakers for each. It is essential to use a suitable chip breaker based on the desired depth of cut, feed rate, spindle speed, and the desired surface finish.
