I am milling a piece of aluminum that is .188 thick. It is clamped to a piece of aluminum that i flycut flat. I am trying to make a pocket -.075 deep in the aluminum. I can seem to get the pocket flat. I get .02 difference from side to side. I am using a indexable 5/8 single insert end mill know. I thought if i followed with a carbide 1/4 ...
Without a lathe or milling machine, the only ways to shape metal are files, saws and grinders, either angle or pencil type. I use all three for simple shaping operations. If you need to drill holes, a hammer, center punch and drill press will work. Another way to shape steel is a torch, you can heat it to about 1,500 degree and bend it to shape.

6061 Aluminum milling. Post by mrgilder » Mon Apr 30, 2012 3:39 pm. Is there an ideal feed rate and router spindle rate for cutting into aluminum with either a 1/4" or 1/8" flat end mill (1/8" max depths in several passes.) with HHS bits? I have a 2 1/4" hp router and I am starting at 20 ipm feed rate Thank you Jerry. Top. Loudspeakerboy

Machining process: cutting speed for turning, drilling, reaming, and end milling. 3. Please note the table is applicable for high speed steel tooling, when you use carbide tooling, increasing or decreasing the cutting speed based on cutting tool hardness, for example, multiply the listed speeds by a factor of 2 to 4, and the speed should be ...
Milling aluminum. I've done a little machining of aluminum on the Shark. The results were mixed - encouraging, but not good. And sometimes frightening. Light cuts, in the .015-.025" range, tend to be the rule to the non-rigid nature of the machine. Sticking with smaller end mills, 3/16 to 1/4, is strongly advised.

Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.
Grinding, or abrasive machining, once performed on conventional milling machines, lathes and shapers, are now performed on various types of grinding machines. Grinding machines have advanced in design, construction, rigidity and application far more in the last decade than any other standard machine tool in the manufacturing industry.

Cutting tools for metalcutting have many shapes, each of which are described by their angles or geometries. Every one of these tool shapes have a specific purpose in metalcutting. The primary machining goal is to achieve the most efficient separation of chips from the workpiece. For this reason, the selection of the right cutting tool geometry is critical.

Aluminium exhibits high thermal conductivity and therefore the chips produced when machining aluminium transfer high levels of generated heat, resulting in significantly reduced thermal loading of the cutting edge. Due to these properties, milling aluminium is characterised by extremely high cutting speeds and feeds.
An electrochemical machining (ECM) is to be used to cut a through hole into a 12 mm thick aluminum plate. The hole has a rectangular cross-section, 10 mm × 30 mm. The ECM operation will be accomplished in 2 minutes, with efficiency of 90%.
So I know this topic comes up a lot but I'm still confused. My question regards cutting feeds and speeds in 6061 and 7075 aluminum. the majority of our machining is done on a Haas Mini Mill. During roughing i have an rpm of 2400 and a feerate of 11 (guessing its inches per minute). Now that gives me a chip load of 0.0011.
Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1) Where R is a radius of a milling cutter. (Formulas are referenced later by the number in parentheses.) The concept of calculating tangential cutting force ...
Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...
Milling aluminum appears to be a remarkably easy process. Often, people who are not directly involved in machining aluminum hold misguided views. They believe that it's enough to take a balanced, sharp, polished tool and rotate it at a maximal speed, set at medium feed and the material will cut like butter.

I got pretty good at tapping by using this technique: -Clamp workpiece in drillpress or mill vise and locate hole to be d+t. -Drill with correct size drill for tap (work up in stages if it's a big hole) -Without moving or unclamping workpiece, put the tap in the chuck. -Apply a bit of A9 for aluminum or TM or whatever.
