Fine-Tuning a Bandsaw

Fine-Tuning a Bandsaw
Vibration and wandering cuts are signs your bandsaw needs a checkup
by Robert Vaughan
Check the crown and drive train—To see whether a bandsaw needs its wheels crowned, you don’t have to remove the wheel. First remove the wheel guards, and back off the blade-guide components. Install a -in. blade, and set the tension normally. Adjust the tracking so the blade stays in the middle of the tire when the wheels are turned by hand. With a scrap of wood, push on the back of the blade using the same kind of force you’d use for cutting wood (see the photo at right). Hold the block in place for three or four revolutions of the blade, and then release the pressure against the blade and turn it a few more times.
If the blade’s position on the tire surface doesn’t change even though the blade deflects slightly from the pressure of the wood block, then the crown is in good shape. If the band moves off the center position under pressure and returns when pressure from the wood block is released,the crown is showing signs of wear but is still functional. If the blade moves and doesn’t return to its original position, then crowning is needed. You can do this yourself (see FWW #95, pp. 50-53).
Tires need replacing from time to time. Most machines that have less than a 16-in. capacity use a rubber-band type of tire. Larger machines may have tires of a specialized configuration; some have a fitting groove in the middle of the wheel’s surface. When ordering replacements, note your saw’s model number; I’ve seen different tires used on similar models. While you’re in the machine’s innards, examine the saw’s pulleys. Those that are worn or bent can cause vibration. Worn belts develop knots at the factory joint, creating a bumping sensation. Replace these inexpensive items when they show signs of wear. And check all bolts and setscrews for tightness.

Fine-Tuning a Bandsaw
Vibration and wandering cuts are signs your bandsaw needs a checkup
by Robert Vaughan
An improperly adjusted bandsaw will do everything but cut well. It may throw, break or dull blades quickly. Or it may produce cuts that wander like a drunk failing a roadside sobriety test. I’ve performed surgery on a lot of bandsaws, and I have discovered there’s no single saw component that causes most ills. Many jumping and tracking problems can be traced directly to wornout tires. But a vibrating bandsaw may just as likely be handicapped by a beaten-up drive belt. A saw that refuses to cut squarely may be affected by a guidepost that is out of alignment, or the saw may have one of its wheels out of line (see the box on pp. 78-79).
Solving many of these problems doesn’t require a lot of fancy equipment. Basic tools such as wrenches, try squares, a file and some washers for shims are often all you need. A few diagnostics and adjusting techniques will bring out the best performance your saw has to offer. The basics include checking your tires for wear, wheel alignment, guidepost alignment and adjusting the guides and blade tension. Begin your tune-up by unplugging your machine. Tires must be smooth and crowned
I begin a tune-up by opening the wheel housings and blasting the works with compressed air to clear out the sawdust. Then I look at the wheels and tires. If a wheel is broken or badly bent, there’s not much you can do except replace it. If your bandsaw tracks poorly or jumps excessively, chances are the tires are worn. The majority of bandsaw tracking and jumping problems begin and end here. Tires should be whole, not missing large chunks, and without hairline cracks.

The surface should be smooth, clean and slightly crowned (see the top photo). The crown defines where the blade tracks. Blades have a tendency to wander back and forth on the surface of uncrowned tires. A crown also keeps the teeth from cutting grooves in the tire’s surface. A grooved surface will make tracking
unpredictable (see the bottom photo). If you cut a lot of resinous woods, you may have a gummy buildup on the tires, which can create a false crown. That condition can foul the blade’s tracking, allowing it to drift. You can check this by turning on the machine and letting it idle.

Milling

Milling
Cutting Speeds and Feeds, Fluids
The time required to complete a milling operation and the quality of the finish of the machined surface is almost completely governed by the CUTTING SPEED and FEED of the cutter.
Cutting Speed refers to the distance, measure in feet, a point (tooth) on the circumference moves in one minute. It is expressed in terms of FEET PER MINUTE (FPM) and is directly dependent on the REVOLUTIONS PER MINUTE (RPM) of the cutter.
Feed is the rate the work moves into the cutter and is given as FEED PER TOOTH PER REVOLUTION (FTR). The selection of the proper feed is probably the most difficult thing for the machinist to determine. In view of the many variables; width of cut, depth of cut, condition of the machine and cutter, etc., feed should be as coarse as possible and consistent with the desired finish.
Consult the mill manual or wall chart for the speeds and feeds required for various materials.
Cutting Fluids serve several purposes. They carry away the heat generated during the machining operation, act as a lubricant and prevent the chips from sticking or fusing to the cutter teeth, and flush away chips. The lubricating qualities also influence the quality of the finish of the machined surface.
UNTIL YOU BECOME PROFICIENT IN THE USE OF THE MILL, CONSULT YOUR INSTRUCTOR OR SHOP PERSONNEL BEFORE STARTING ANY MACHINING!

Motion and coordinate system for CNC machine

admin — Sat, 05 Mar 2011 09:50:16 +0000

Motion and coordinate system for CNC machine
Z-axis: Always aligned with the spindle that imparts cutting power. This spindle might rotate the work-piece as in a lathe, it might rotate a tool as in a milling machine. It is perpendicular to work-holding surface if there is no such spindle. Positive motion in z axis tends to increase the separation between the work-piece and the tool
X axis: Positioning the moving element, parallel to the work-holding surface, horizontal (if possible).
On machines with rotating work-pieces, it is radial and parallel to the cross-slide
On machines with rotating tools,
1. If the Z-axis is horizontal, the positive x motion is to the right when looking from the spindle to the work-piece.
2. If the z axis in vertical, the positive x axis is to the right when looking from the spindle to the column
On machines with non-rotating work-pieces and non-rotating tools, the xaxis is parallel to and directed toward the principal cutting direction
Y-axis: be in such a direction as to complete a right-handed Cartesian coordinate system

Motion control system
- Point to point
- Straight cut system
- Continuous path
    · Linear path interpolation
    ·Incremental path approximation
    ·Interpolation using circular or other equations
