Long lengths of engagement with high percentages of thread (small drilled-hole sizes) do not significantly increase the strength of the fastened threads. In fact, in some cases, it has been proven that long lengths of engagement can actually reduce assembly strength because of accumulated thread errors that are more likely to occur with high percentages of thread. So resist the urge to use longer fasteners and high-percentage threads in an attempt to strengthen threaded assemblies.

If tap/drill charts are not adequate for today’s machining practices, then how do you establish proper drill size? For a start, keep in mind these factors:

As drill recommendations were being developed for standard-size coarse (UNC) and fine (UNF) series threads, drill sizes were selected based on tests showing that a standard, general-purpose, jobber-length drill - having a standard 118° point angle - will produce a hole size larger than the measured drill diameter. This became known as the "probable hole size," which is often listed on tap/drill charts next to the decimal equivalents of the drill sizes (Table 1). For example, a No. 7 (0.2010"-dia.) drill will, on average, produce a hole that is 0.0038" larger than the drill’s diameter. This would result in a drilled hole size of 0.2048", approximately 70% of thread height. Compared to the minor-diameter specifications for a 1/4-20 UNC-2B tap (0.1960"- to 0.2070"-dia.), the finished hole size is near the high limit, 0.0022" under the maximum minor diameter (Table 2). The drill is removing as much material as possible from the hole, reducing the load on the tap. This makes tapping easier and reduces the possibility of tap breakage. And staying below the maximum minor diameter prevents the production of threads that are too shallow.

Choosing the right automation to pair with a CNC machine tool cell means weighing various factors, as this fabrication business has learned well.

Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.

When mounted in the five-axis machining head, the saw can make straight cuts or angled miter cuts and compound miter cuts. Because the saw can be manipulated in five axes, it can cut from either or both sides of the workpiece. The saw can make multiple cuts to form intricate notches. It can also serve as a cutoff tool. With the proper blade and appropriate cutting speeds, sawing can be performed on aluminum, steel and other materials such as composites and plastics.

Now look at the longer lengths of engagement. As the engagement increases, the recommended drilled hole size before tapping gets larger. From 2/3d to 1 1/2d, the predrilled hole size recommended is 0.2020" to 0.2070", or near the high limit. This range is often referred to as a "1-diameter" length of engagement. Tap/drill-chart recommendations are generally based on this length.

Engagement of a tool’s cutting edge with a workpiece generates a cutting force. Such a cutting force combines tangential, feed and radial forces, which can be measured by a dynamometer. Of the three cutting force components, tangential force is the greatest. Tangential force generates torque and accounts for more than 95 percent of the machining power. See dynamometer.

Determining the shape of a workpiece is required in many manufacturing processes. Keep in mind these important points to ensure that you master the process.

The drilled hole must be within the specification for the class of thread. The drill selected should produce a hole size that falls between the minimum and maximum minor diameter for the class of thread. For example, for a 1/4-20 UNC-2B thread, any drill that produces a hole between 0.1960" and 0.2070" in diameter could be used. Once the hole is drilled, it is important to gage the hole to verify the size using pin or plain plug gages matching the minimum and maximum minor-diameter specifications. Dimensions for the minimum and maximum minor diameter of screw threads are available in many publications. The ASME industry standard B1.1 is one of the best sources for this information.

The workholding system features a series of programmable clamps that release the workpiece on command so that it can be lifted and repositioned. This prevents interference between the clamps and the machining head. Drilling, slotting, milling, tapping, notching and cutoff can be done in one setup, completing operations to all four sides of the workpiece and to the ends. An inverted tooling extension allows milling and other operations to be performed to the underside of the workpiece.

While it is best to use the largest drill size possible, doing so may adversely affect the strength of the threaded assembly in some situations. If, for instance, the internally threaded part or nut were made of something thin, such as heavy-gage sheet metal, the one or two threads in the nut might not be strong enough to support the load when the screw is tightened. Therefore, for thin parts the smallest drill size is recommended for the highest percentage of thread to keep the threads as strong as possible.

Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.

In extreme cases in which the length of engagement is greater than 1 1/2 times the thread diameter (1 1/2d), the hole size can be enlarged to 0.2100", or 0.0030" larger than the maximum minor-diameter limit of 0.2070". The additional threads in the engagement allow the height of threads to be reduced while maintaining the assembly strength. However, caution should be taken before applying this rule. It is the engagement between the two parts that allows the use of the larger hole size, not the depth of the tapped hole. If the tapped hole were 3/4" deep and the screw were only 1/4" long, the engagement would be 1 diameter and this rule would not apply.

As the length of the thread engagement between the nut and screw, also known as the length of engagement becomes longer, there are a greater number of threads contributing to the strength of the assembled nut and screw; therefore, the hole size can be enlarged. In summary, drill close to the minimum minor diameter in thin parts and near the maximum minor diameter in longer assemblies.

Adding pallet systems brought Mach Machine success and additional productivity. The shop has since furthered its automation goals while adding new capabilities.

For example, the recommended drill size for a 1/4-20 UNC thread is a No. 1 (0.228"-dia.) on a tap/drill chart. However, the principle of oversize drilling or probable oversize applies to these recommendations as well. Since high-performance drills produce smaller holes, the drill diameter may have to be enlarged to prevent tap breakage or rough threads due to excessive material displacement. As with holes drilled for thread-cutting taps, the size of the hole is far more important than the diameter of the drill used to make it.

Determining the shape of a workpiece is required in many manufacturing processes. Keep in mind these important points to ensure that you master the process.

Today’s advanced drills - powered by more accurate, higher speed machine tools - are producing holes much closer to the actual measured size of the drill, or even smaller than the drill diameter. Producing smaller pretapped holes substantially increases the workload on the tap. Changing to one of these advanced drills could result in tap breakage where none existed before. The standard No. 7 drill may no longer be the correct drill size for a 1/4-20 UNC-2B thread. It may require a 13/64, No. 6 or even a No. 5 drill to produce a hole that’s 70% of thread height.

Whether cutting or forming threads, the practice of using the tap to produce the minor diameter of the thread is not recommended. While using taps to produce the minor diameter is not a good idea, taps can be used to help eliminate "spin-down" burrs formed below the minor diameter in the part during tapping. Taps used for this purpose are called "controlled root" taps. The minor diameter of the tap is controlled to the size of the drilled hole in the part. During tapping, burrs produced at the minor diameter are "clipped off" by the tap’s minor diameter, leaving the thread smooth. Burrs generally are small and should have little effect on the cutting force. If, however, the tap is called upon to remove more material than small burrs, the cutting or forming force could exceed the breaking torque of the tap.

As the demand for faster production cycles continues to grow, the ability to produce high-quality parts quickly and efficiently has become increasingly important. High-speed 3D printing has emerged as a key solution to reduce lead times and increase productivity across industries. However, like any advanced technology, it comes with its own set of challenges. In this webinar, Forward AM will explore both the opportunities and hurdles of adopting high-speed printing with a particular focus on overcoming those challenges. It’ll start by discussing the fundamentals of high-speed 3D printing and how it differs from conventional 3D printing methods. It’ll then move on to the key factors that influence successful implementation, including the impact of materials, equipment and design considerations. One of the main hurdles in high-speed 3D printing is ensuring the right balance between speed and part quality. Different materials behave differently under high-speed conditions — and not all equipment is optimized for this process. Forward AM will showcase some validated materials and equipment that are proven to perform well under these conditions. In addition, the presenters will look at real-world examples and applications where high-speed 3D printing has been successfully implemented, highlighting the collaboration between designers, engineers and manufacturers.

To determine the proper hole sizes that maximize strength for various lengths of engagement, consult the ASME standard or other commercial manuals containing this information. Looking at the recommended hole sizes for a 1¼4-20 UNC-2B thread (Table 3), the lengths of engagement are listed in terms of thread diameters. In other words, "1/3d" indicates the length of engaged threads between the nut and bolt when assembled. One-third of 1/4" thread diameter is 0.083". This means that if a 3/4"-long bolt were threaded into a 0.083"-thick nut, it would be said to have a length of engagement of 1/3 of the diameter (1/3d). Notice that for this short length of engagement, the hole-size range recommended for a class 2B thread is 0.1960" to 0.2020", or near the low limit.

Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
