What To Know About Face CNC Milling as Machining Procedure
Face milling is a method that smoothens and flattens workpiece surfaces. There are two forms of machines that machinists choose for the process. The devices include; a milling machine or a machining center. There is a major difference between the traditional and modern milling processes. Whereby the milling machine is perpendicular to the workpiece in the modern method. Such a set-up allows milling on the top side of the workpiece, leaving the sides. At Creatingway, we use face milling to aid us during the CNC machining. Our experts know various tips and operations to improve your project quality. Here are some of the knowledge concerning Face milling as a machining procedure.
How to Face Milling Process Work？
The face milling technique can either be automatic or manual. The feed rate of the machine differentiates the two. Manual ones require regular stoppages for one to move the workpiece across the platform. As for automatic machines, they remain more constant, limiting possible errors. The technique uses tools like fly cutters, end mills, and shell mills. The face milling machine moves counterclockwise, moving the item across its teeth. There are four methods involved in milling workpieces.
Adjustment of the spindle Speed and Feed Rate
It is important to maintain the speed and feed rate the machine uses. Such a precaution ensures that workpieces obtain precise cuts at specific angles.
Position the Workpiece Correctly
Before initiating any procedure, ensure that the item is firmly attached to the table. Such a grip allows effective machining as the workpiece doesn’t slip.
Machine Your Workpiece
Once the machine set-up is complete, the machining process starts. Whereby machining codes get fed into the computer facilitating face milling. Then, the computing continues until the desired outcome is fully met.
Position the Milling Machine Correctly
it is essential to ensure the milling equipment is in the correct place. Most machines get placed perpendicularly to the workpiece. Such an adjustment allows the cutter to work on the top effectively.
How To Choose the Right Cutting Tool for Face Milling
For any face milling to succeed, the tool used must be appropriate. One must identify the different equipment available. Such tools include end mills, fly cutters, and shell mills.
The cutting edge in end mills enables superb finishes on an item. Such a method is appropriate for cutting off small chunks of material. Also, it is limited to specific material options as it is not that strong.
Fly cutters possess only one kind of insert and cutting edge. Such an adaption enables fine finishes consuming little power. The low power makes the fly cutters operate at low speeds. So, fly cutters are cost-effective tools that produce outstanding finishes.
Shell mills posse’s numerous teeth joined with inserts on its ends. Such a modification allows consistent surface finishes. The design enables the machinist to gauge the amount of material eradicated per time. The constant change of the inserts relies on the nature of the material.
Essential Tips While Choosing the Correct Tool in Face Milling
- The spindle must match the machine’s speed to avoid easy wearing out of face mills. Such a factor elongates the tool’s lifespan saving on economic costs.
- Don’t face the mills over the slots or holes as it causes exiting. Also, reentering is evident, slowing down the process rate and hindering efficiency.
- To face mill softer materials, use a fly cutter. The energy required to power the tool is low, leading to a corresponding low exertion force.
- To face mill harder materials, use a shell mill. The tool contains numerous cutting ends, allowing the removal of greater pieces at a given time.
- One should consider the angle at which the tool enters and leaves the item. Most enter at 450 or 900, others 10-65o.
- An end mill creates the best aesthetic designs under the face milling method. The cutter found in the tool contains multiple teeth essential for creating different designs.
What Are The Forms of Face Milling Operations?
High Feed Milling
The technique involves methods using high feed rates and cutting speeds. Also, low entering angles are part of the features suited for the procedure. Here, cutting speeds reaches over 1000m/min.
General Face Milling
This technique doesn’t need any special attributes. Although, the entering angle is a considering factor. Face mills with an entering angle of 450 are the best forms to use. Also, the diameter of the workpiece should be smaller than the cutter.
To acquire a superb surface finish, use wiper inserts. Their lengths vary with a variety of right and left-hand versions. The urgency of wiper inserts increases with an increase in feed per revolution.
Heavy Duty Face Milling
This form of machining involves large machining centers and huge materials. Such sizes need high amounts of horsepower to inhibit mobility. Tools having an entering angle of 600 are the best as they possess high feed rates that boost productivity by cutting more material.
In conclusion, face milling is a basic process that smoothens surface parts. At Creatingway, we use the method as part of our surface finishing process. Our experts major in perfecting your workpiece’s outcome at an economical cost. Also, you can acquire the desired finish by boosting quality and efficiency.
