Tutorial with several tips and tricks. Using a rotary table, dealing with backlash, edge finding and more.

So I have never had to do this before in my career as a machinist. I have a part that needs a radius milled into the back side of it that runs the entire length of the part. The radius that needs to be machined is .475". I have a 1/2" Ball end mill in my machine, ready to start cutting, but I have no idea where to even begin.

To avoid this problem we need to create a final line that goes straight up (positive) in Y and does not change in X. This will create a 90-degree corner that will allow the mill to finish off the corner. The green arrow is our leaving block. …

Cutting a arc on manual mill. Aug 03, 2010 0183 32 Note the small diameter end mill it will take longer with a less-nice finish, but the small diameter imparts a lower torque on the part from the machine spindle, long handle high torque on part by operator, operator standing outside the radius of handle and helix direction machine does not spontaneously disassemble your fixture...

This will create a 90-degree corner that will allow the mill to finish off the corner. The green arrow is our leaving block. Note how it allows the tool to go all the way into the corner before we cancel the radius compensation.

By adding a generous radius, as shown on the far right, the cut-out can now be machined from the top, with the hole and cut-out being completed in a single setup. When multiple CNC milling setups are required, be aware that re-orienting the part in the machine creates more possibilities for positional errors. Maintaining a tight tolerance ...

Touch off that edge for a 0 and back away the radius you want. Mount an adjustable boring head and put in a boring tool to almost touch the work, advance until it just starts to take a cut. At that point you can incrementally advance the axis, leaving the boring bar alone, until you have the cut to the depth you want.

The I, J and K values in circular interpolation are from the centre of the TNR (lathe), and centre of cutter (mill) to the centre of the radius being programmed, when Cutter Radius Compensation (G41/G42) is not being used. Accordingly, the I value shown the the example code of my Post #2 is 0.75 - 0.03125(TNR) = 0.7188, rounded.

To do this in a vector graphics program, you make a circle with the radius of your bit centered at the corner, translate it by the values in the diagram X = Y = sqrt (R^2 / 2) and do a boolean union operation with the inside corner. Outside radius techniques - practicalmachinist.com More

Tue Sep 23, 2003 3:37 pm. On a mill, the easiest way is to use the rotary table and a fly cutter. Assuming a vertical spindle mill, set up the rotary table horizontal. The fly cutter can be set up for about a 2 or 2 1/2" cutting diameter. Tilt the mill head and set up so that the fly cutter just passes over the center of the aluminum plate.

Radius_1. The upper one could be done with Parallel, but even there I get some strange passes: Radius_2. But to mill the second radius (vertical-horizontal-vertical), in my opinion, the best strategy would be to follow …

Step 7: Method of Use. Firstly the radius gauge is placed on a flat surface and the digital gauge zeroed. Of course the same can also be done with a dial gauge. When setting the zero and doing the measuring, the gauge should be held square to the work piece. I rest it against a square to ensure that it is upright.

Datron offers a line of edge radius tools that can machine a pristine radius along a workpiece edge or internally within a contour. These long-life, micro-grain carbide tools are available in various radii, shank diameters, and geometries for specialty applications. From a slight .5mm radius to a larger 6mm radius, we offer a line of multi ...

Radius_1. The upper one could be done with Parallel, but even there I get some strange passes: Radius_2. But to mill the second radius (vertical-horizontal-vertical), in my opinion, the best strategy would be to follow the curve/direction. I have tried to use Morph, but there is a problem, that the path is not going to the end of the radius.

1. Some Dykem, scribe a layout, some careful grinder work, a file. 2. build a fixture that allows the part to pivot securely about the center of the radius, attach a long bar for control, and hand pivot the part against the cutter. Not a good time for climb milling.

Radius gauge the outside curve or insert a wood plug in the hole and pickup the radius using dividers. Rough the blank on the band-saw then drill, bore, and ream the holes. Make a pin for each of the hole diameters. It's useful if the pins have a tapped hole in the end for a hold-down clamp.

Design milled areas so that the end mill required is limited to 3:1 in length to diameter ratio. As shown in the figure below, longer end mills are prone to chatter. When designing a three-edge inside corner, one of the inside edges must have the radius of the end mill. This is illustrated below. Also shown below is how a separate hole can ...

Make sure the vise grips it full contact. .875 thick should support itself with no problems. Center up on the blank to locate the radius as needed. You will need to step into the cut about .050/pass to a depth just short of the vise jaws.....Same goes if you mounted the vise to the rotary table to swing the radius cutting with an endmill cutter.

Ball nose end mills make excellent form tools for inside radii. Sometimes you need to run the machine in reverse of course. For outside radii the cheat is: a corner rounding end mill. Use it like a form tool. Bonus is you get four cutters of the same size.

On a mill, the easiest way is to use the rotary table and a fly cutter. Assuming a vertical spindle mill, set up the rotary table horizontal. The fly cutter can be set up for about a 2 or 2 1/2" cutting diameter. Tilt the mill head and set up so that the fly cutter just passes over the center of the aluminum plate.

A smaller cutting tool requires the CNC milling machine to run at a slower speed and takes longer to remove material. Also if the milled pocket is deep, a larger stronger cutting tool will need to be used. This means a larger radius would be required. A rule of thumb is to keep the corner radius greater than ⅓ cavity depth. Read On
