Two of the most important factors of a good workholding setup are stability and access. Both have a direct connection to right-size workholding, and finding a balance between the two is needed. The fixture may be large and provide rigid holding, but increases the chances of access to the workpiece being limited—and vice versa.

-This method can achieve high material removal rates and is faster because it removes very large amounts of materials within a short time.

End milling is a fundamental type of cutting.Cutting utilizes a revolving wheel with blades, an end mill, to get rid of material from the opposite comes in. Unlike many other types of milling operations, the end mill can be precisely customized to the diameter and depth to ensure precise cuts with proper shape. The process is extremely flexible able to produce a number of geometries such as slots, contours and complex profiles.

Face milling is a metalworking process which is used to cut flat surfaces or faces, generally by using face mill cutter. The operation is inherently rotational, with the face mill cutter providing multiple cutting edges on the cylindrical body or periphery. To understand this type of cut better, imagine the cutting edges on a milling cutter are slicing through the workpiece material in two parallel motions relative to one another.

Work holding devices in milling machineppt

Face milling process The workpiece is generally clamped on the machine tool, either a milling machine or machining center according to type, where face mills cutter is installed and then rotates via the spindle. The cutter and the piece of work are correctly adjusted, where after the desired depth of cut would be set on the cutter. As the cutter’s face (usually with a large number of blades) rotates along a horizontal axis, the cutting edges on the as-cutter-face bottom remove material from the workpiece surface to produce a flat surface area or face.

End milling is achieved most commonly by using a particular type of milling machine that imparts the cutting tool with the required rotary motion, and the balance of the operation ensues with the guiding of the workpiece to the cutting tool.

Choosing workholding that accommodates the shape of your part really comes down to whether it’s round or prismatic (has flat sides). If the parts are prismatic, most often a vise will do just fine. If the part is round, you’ll need to hold on to an outer or inner diameter on the part. This may require a collet chuck, lathe chuck or V-blocks, if it needs to go into the mill and so on.  Knowing if what’s coming through will be raw material, a casting or partially finished parts, will also indicate what the workholding will have to accommodate. For example, a round raw bar from the mill may have an OD tolerance of ±.005", but if a part is cast, then the size may be ±.02"—could be better, could be worse. If a part has already been machined, then the size is not a variable, it’s a known controlled value.

When it comes to securely and accurately situating material on a machine table, there’s often more than one way to get the job done. Are they all as precise or productive? Probably not, but they’ll get the part to the next step of the process. Everything will seem to be running as planned, but over time a scrap part here, or slow down there, and the cost of taking the easier or cheaper route adds up.     That said, if you get into a situation where you know the part can’t be made with any of the fixtures around the shop, or production rates just aren’t keeping up, there are fundamental factors to understand before setting out to find a new device. These will vary in importance from shop to shop and some will be easier than others to assess. Understand these four things about the job, and we promise you’ll find the best workholding device for any project.

While we often think of robots or assembly lines when we think automation, when it comes to workholding, the focus is largely on the ability to clamp and unclamp the part or fixture repeatably and accurately, typically with the help of air or hydraulics. There are three levels of automation for consideration in workholding.

Several milling tools and machinery are used in the material removal technique of face milling. The primary tool is a face mill cutter in various different face mill configurations for different workpiece size and material.MaterialsFace mill cutters are usually made of high-speed steel (HSS) or carbide, and are similar to fly cutters on your boring heads with reliable inserts for spares. HSS Face Mill Cutters,HSS Roughing End MillsManufacturersRecommended operating speeds depend on the specific cutting tool manufacturer’s recommendations based upon a material’s tensile strength.

-The heat produced during face milling can change the surface finish and dimensional accuracy of the workpiece, particularly if efficient cooling arrangements are not made.

-Machining is performed in deep cavities by long-end mills, which produce high tool overhang and, subsequently, risk deformation or chatter.

Other functions of the cooling and lubricating fluids include improvement of tool life as forces to cutting are reduced and improvement of the surface finish of the work material, including chips.

Moreover, different workholding tools such as vises, clamps or fixtures clamp the workpiece during milling.The use of cutting fluids or coolants may also be common when dissipation of heat is needed, surface finish and tool life are affected. Safety goggles, gloves and clothing are important attires that anyone operating a milling machine cannot do without.

How automated is your loading, unloading, clamping, etc.? Or, what investments are planned for your shop’s automation, and will any of it be for machining? Workholding is a key consideration if any automation is in the works. If not, you’ll still need an understanding of who will be handling workholding, how many people, experience level to choose correctly.

– End mills are used for the machining of shafts, sleeves, levers, and pulleys to provide keyways, axial and circumferential grooves, profiles, etc.

A machining center or milling machine may be used to face mill the workpiece into a program controlled shape. This machine is equipped with a spindle that rotates the face mill cutter and a table or fixture, which holds the workpiece securely into place. Milling machines are either manually operated (for simple parts) or computer numerically controlled (CNC) for complex and/or high precision parts.

The first step is to clamp the workpiece to stabilize it when machining. Then, the machining starts by advancing the end mill into the first point of the cut. Material is removed while the cutter is rotating and advancing along the path programmed in the tool, which may comprise the shape of a straight line, curve, or complex form.
