In simple linear turns, the cutting tool moves along a line parallel to the axis of the workpiece so that the finished workpieces always have the same diameter. Therefore, to rotate the taper, the workpieces must be installed on the lathe so that axis of rotations are at an angle to the axis of the lathe, or the cuttings tool moves a lathe at an angle relative to the axis of the bend. When the diameters of a piece change uniformly from one end to the other, the pieces are called a taper.

Taper turning is a machinings operation, which means that the diameter of cylindrical workpieces gradually decreases from one part to another. The taper can be external or internal. If the workpiece is taped outward, it has an outer taper. If it is taped inward, it has an internal taper. In a tapered piece, the diameter of the workpiece varies uniformly from one end to the other. The workpiece can be taped from inside or outside. The workpiece must be positioned in such a way as to make the taper such that the axis of rotation is at the angle to an axis of the bend.

When using any method to make the taper, the cutting edge of the tool must be placed on the center of the axis of the workpiece. If the cutting edge is not properly positioned at the center of the axis of the workpiece, the workpiece will not actually be canonical, and the taper rate will vary with each cut out. Different Types of Taper Turning Methods: 1. Form Tool Method The form tool methods are one of the simplest methods to create a short taper. The tool used in thises method is called the taper turnings form tool.

The tool itself is used in a tapered shape, creating a tapered workpiece. In this method, the length of the taper should be less than the length of the tool cutting edge. Since the entire edge removes the metal, it will create huge vibrations and therefore requires a large force. This method is performed to reduce the required vibration and force at a slow rate. In thises method, the axis of rotation of the workpieces is shifted to the axis of the lathe at half an angle to the taper.

The workpiece is placed between the live center and the dead center. The tailstock is moved upright in a cross direction that is in the direction of the lathe axis by the turning set-over method. The tailstock is locked in an upward or downward direction to allow the workpiece to tilt, and therefore the taper bend can be ejected. Compound Rest Method This method is typically used to produce short and steep cones. In this method, the compound rest is rotated at the required angle and held in position.

The compound rest can be rotated up to 45 degrees. Internal and External Broaching 4. Taper Turning Attachment Method In this method, the taper bend is performed using an attachment. The guide bar can swing at any required angles of the taper. The tool moves parallels to the guide bar. A guide bar is used to guide the tool at required angles.

The guide bar has a scale of degrees. The angle required for taper turning is achieved by rotating the guide bar. In this method, the workpieces are held in a chuck. It has a guide block that attaches to the back end of the cross-slide and runs on the guide bar.

In this method, the guide bar is set at an angle at which the workpiece is to be taped. By using the taper turning attachment method, taper turning of any size can be performed easily. The job is held either in Chak or in the centers, i. The depth of cut is given by the compound rest handwheel.

This method does not require disturbing the alignment of the lathe and therefore reduces operator effort. A very wide range can be produced using these methods.

It can be used for mass production. Some engine lats have a prebuilt taper attachment, and most manufacturers have a taper attachment available. Combining Feed Method It is an advanced tempering method. In some lathe machines, both longitudinal and cross feeds can be mounted simultaneously, causing the tool to be moved in a diagonal path and taper bent. The diagonal path followed by the instrument is the result of two feeds. The direction of the tool can be changed by varying the feed rate of longitudinal and crossfeed.

This method can only be operated by a skilled operator because it is very easy to do wrong in this method. FAQ Taper Turning Taper turning is the turning process in which the cutting tool moves at an angle to the axis of the workpiece so that a tapered shape is obtained in the workpiece. In a tapered piece, the diameter of the workpiece changes uniformly from one end to another.

The workpiece can be tapered from inside or outside. Taper Turning Methods.

Posted on 8-September by mathscinotes Quote of the Day Luck usually visits me at 2 am on a cold morning when, red-eyed and bone-weary, I am pouring over law books preparing a case. It never visits me when I am at the cinema, on a golf course or reclining in an easy chair.

Building a steam project will require some basic machining and I have been brushing up on the subject. I need to decide whether to build something custom HP made me take a machine shop training course years ago or assembling a kit. I decide to do a bit of research on machining steam parts and I encountered a paper on measuring the taper of a hole using gage balls.

Figure 1 shows an example of gage balls source. This was the first time I have seen an application for gage balls and I thought it was worth documenting here. I will derive a formula that I saw in the discussion mentioned above for determining the taper of a hole by determining the depth that two different diameter balls will drop into the hole.

Analysis Figure 2 shows the diagram I will use to derive the formula. I will need four pieces of information to compute a taper angle. R is the diameter of the large gage ball.

The gage ball diameters are measured by the manufacturer, so I need to make two depth measurements. I can compute the taper by substituting the two depth measurements and the two gage balls radii into Equations 1. In the derivation, I equate the length of the of the hypotenuse of the triangle formed by the ball of radius determined two ways: 1 using the half-angle and the radius R, and 2 using the measurements that were taken d1 and d2.

Figure 3: Derivation of the Taper Formula. To illustrate the use of Equation 1, I present an example in Figure 4. Figure 4: Taper Calculation Example. I show the associated calculations in Figure 5.

Figure 5: Computations For Example in Figure 4. The formula worked pretty well considering the tolerances involved. I should comment that handling these small gage balls could be a problem. I did notice that you can buy them with handles , which should make using them easier. By the way, only one of the gage balls needs to go all the way into the hole. Here is an example from the discussion mentioned above and how I worked the problem. Note that the gage balls had four digits of significance in their diameter specification, but the drawing only showed three digits.

For more information on using gage balls, see this reference. Figure 8: Another Worked Example.
