what is milling? climb vs. conventional milling process

Do you know one important difference between a Lathe Machine and Milling Machine? Any guess? Unlike in a Lathe where the tool is fed against the revolving work-piece, in a Milling Machine, the work-piece is fed against a revolving multi-teeth tool (Milling Cutter).

Your milling machine is the second most important machine tool after the lathe machine in terms of versatility. Your milling machine can machine flat, curved, or irregular surfaces and also do drilling, reaming, boring, and many other operations.

Your milling machine can be classified as Vertical or Horizontal, based on the orientation of the spindle. Further, your milling machine can be knee and column-type, fixed bed-type, ram-type, planer-type, turret-type, etc. Your milling machine has a spindle with an independent motor, pressurized cooling system, variable spindle speeds, and feeds, manual and power-operated table feeds (including rapid movement). Some of your milling machines have more than one milling head, either vertical or horizontal, or a combination of both.

Your milling machine has movements in the X, Y, and Z-axis, depending on the design of your milling machine these movements are given to the table or milling head; also, the movements may be distributed between the table and the milling head. Many of your milling machines have spindle movement through a quill unit.

Most of the milling machines you use are of conventional Knee and Column type and others are fixed-bed-type, where a fixed bed takes the place of the knee. Structural parts of your milling machine are made from cast-iron since cast-iron has good shock absorption quality.

Quill-unit: In your milling machine, the positioning of the work-piece and milling is accomplished by using movement in X, Y and Z axis. With the arrangement of the Quill-unit, you can move the machine spindle for giving depth of cut. Your Milling Machine may have auto power movement for the quill. . You are able engage / disengage the quill movement or lock the spindle at a particular position.

When you do the up-milling or conventional milling, the cutting forces tend to lift the work-piece and the table on which your work-piece is mounted; up-milling is favorable to the cutter since the starting load on the cutter teeth is at the minimum, however, it results in bad surface finish. You generally use the up-milling process for rough milling and on machines that are sturdy and can withstand the cutting forces.

In climb milling (down-milling), the cutting forces push the work-piece downwards and this helps in milling thin work-pieces and also results in good surface finish. However, Sudden and maximum load on your milling cutter at the start of down-milling is not favorable to the cutter.

The cutting process in your Milling Machine is an interrupted cutting operation, where there is a very small time gap between the exit of one tooth from the work-piece and entry of another tooth into the work-piece.

You have to use a combination of up and down milling in real life to achieve optimum metal removal and surface finish. Properly designed tool geometry, cutting fluid and coolant helps you to achieve this.

In peripheral milling, the axis of your milling cutter rotation is parallel to the surface being machined and cutting is performed by the cutting edges on the outside periphery of the cutter. You can achieve the cutting process by feeding the work-piece against the rotating cutter.

Straddle milling is similar to side milling and cutting takes place simultaneously on two parallel sides of the work-piece; you can do straddle milling by mounting two slotters on the spindle arbor separated by spacers of required width. When you do straddle milling, the two slotters mounted on the arbor work together.

You can use a thin slotter called slitting cutter or slitter for slitting operation; the slitter is thinner than the slotter and has cutting edges on the periphery only. You can use a slitter to mill thin slots or to cut the work-piece into two halves.

In face milling the machined surface is perpendicular to the axis of cutter rotation and you can do face-milling in a Horizontal or Vertical Milling machine. Your face milling cutter has cutting edges on the face as well as on the periphery.

However, the surface finish achieved is inferior to your peripheral milling; also your machine should be rigid enough to withstand the cutting forces and this method is generally adopted for rough milling.

In form milling, the cutting edges of your peripheral cutter or end mill have a special profile and called a form milling cutter. You can transfer the special profile onto the work-piece by milling. You can use the available standard form milling cutters or get one custom made for your requirement.

With a manual milling machine usually, you will have the Z-axis locked and the workpiece is moved in the X and Y-axis. This created a 2D profile on your work. When you want complex 3D profiles machined on the surface of the workpiece you may need to move all the 3 axes simultaneously. The CNC milling machines makes this process easy.

climb milling vs. conventional milling - in the loupe

climb milling vs. conventional milling - in the loupe

There are two distinct ways to cut materials when milling: Conventional Milling (Up) and Climb Milling (Down). The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed. In Conventional Milling, the cutter rotates against the direction of the feed. During Climb Milling, the cutter rotates with the feed.

Conventional Milling is the traditional approach when cutting because the backlash, or the play between the lead screw and the nut in the machine table, is eliminated (Figure 1). Recently, however, Climb Milling has been recognized as the preferred way to approach a workpiece since most machines today compensate for backlash or have a backlash eliminator.

Climb Milling is generally the best way to machine parts today since it reduces the load from the cutting edge, leaves a better surface finish, and improves tool life. During Conventional Milling, the cutter tends to dig into the workpiece and may cause the part to be cut out of tolerance.

However, though Climb Milling is the preferred way to machine parts, there are times when Conventional Milling is the necessary milling style. One such example is if your machine does not counteract backlash. In this case, Conventional Milling should be implemented. In addition, this style should also be utilized on casting, forgings or when the part is case hardened (since the cut begins under the surface of the material). print

This is one of those left hand cutters! How about turning the tool, and cutter the correct direction. G41 climb cutting on the right side. G42 or conventional cutting on the left. Sorry I couldnt help myself.

Great article. Ive had to use conventional milling when for example, Id have my thin unsupported part sticking out of work holding with the tool path contouring around the part (think milling end while cutting a part in a lathe) with the material flexing would cause snapping while climbing because it wants to take a large bite as opposed to ramping the cut in. But yeah, 95% or more is climbing.

Conventional Milling should be utilized on casting, forgings In my head, I logically organize castings as least processed, forgings as most processed, and everything else (hot rolled, cold rolled, extruded) somewhere in between. So to me, that part seems to say use conventional milling for everything, which is obviously not right. Could you show me where I went wrong,? More specific examples, like case hardening, why a particular direction of cut is preferred for a chunk of metal with unknown provenance.

Thank you for the question Dustin! We would suggest conventional milling when your material has a rough surface, such as cast iron, or is anodized because when conventional milling your cut is scooping underneath the surface to remove your material making it easier on your tool. Also, you want to conventional mill when using a dovetail cutter that has a weak neck diameter because this will help relieve the pressure on the neck of your tool.

This is great info. I have always conventional milled with face mill to remove the scale off of titanium. Tool life is increased and getting under that scale to machine it off instead of slamming the insert into the scale each time. Once scale has been removed, go back to climb cutting.

Thanks for this very clear and informative explanation. It has been decades since I worked in a factory. Back then the Bridgeport milling machines had terrible backlash. They would chatter or jump when using climb milling. Plus, if one was approaching the end of a cut, one wouldnt know if the tool would grab at that point and pull the work past the past the desired end point. I almost exclusively used conventional milling and couldnt understand why many people on YT now talk about using climb milling.

A 60 year old worn out manual Bridgeport is all I have to work with. (It is in better shape than my 65 year old worn out body.) I rarely climb mill anything, specially not steel. But if the cut is really light, and I want a good finish, I climb mill. , I apply some drag with the table lock screw, and that seems to eliminate the chatter.

Added uses for conventional cutting: Never climb cut across the end of an upstanding thin rib in aluminum or plastic (You will rip it off). Use reduced feed and conventional cut it or use multiple small depth cuts. Commonly made cutting to length T or L extrusions. Youll only make this mistake once. It helps to conventional cut torched or burnt out steel plate rough profiles first, then switch to climb cut after you mill through the slag. Same principal as case hardened material. Corn-Cob or serrated cutters work nice here too.

I think you left out force vectors during cutting. This can influence tool defection and taper on the side wall on the part. The force vectors are different magnitudes between climb and convectional cutting, so this impacts work holding and this parts or this walls.

I have a Warco 16B milling machine. This is a medium size manual hobby mill. I am confused as people recommend Conventional and Climb milling in about even numbers, this goes for YouTube too. What would you recommend on this type of machine? Your help would be appreciated as I last worked in industry in 1979 so I am extremely out of date. I generally mill Conventionally.

Great question Graham! There are many factors that go into choosing which method is best for you. Please send an email to [emailprotected] with all your information and they will be able to help you out as soon as possible.
