Question #: 3527

Question: How small of end mills are commonly used for cutting balsa? What thickness of balsa can these smaller mills handle?

Current Solution

The size of end mills can vary to extremely tiny to very large cutting diameters. The smaller the cutting diameters, the shorter the available cutting length due to the possibility of breakage. You will first need to determine the thickness, or depth you will need to cut and find the available cut diameters for that depth.

To cut balsa wood, almost any standard 1 to 4 flute end mill will be fine that are intended to be used with wood. The end mill will state the materials that it can cut. Wood end mills will exhibit a flute geometry that is more stretched out to straight.

  • HOW DO I DETERMINE THE AMOUNT OF SCREW WEIGTH THAT MY MOTOR CAN HANDLE

    There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift.

    This formula uses Newtons (N) as it's final unit. Use this with the included radius (R) to determine the torque. Newtons can easily be converted to lbs or ounces using online conversions.

    Effort = Sf + (Load/(2 x pi x (R/p) x Se))

    where:
    p = pitch of the screw
    Se = screw efficiency = Standard lead screw will be between 20% (.2) and 40% (.4)
    Sf = static force. This is the force that is needed to start the movement. The number may be eliminated, but it is good to use a number in the 5 N to 20 N range.
    Load = the expected load that the effort will need to carry (i.e., the router and the included axis assembly that the motor will need to lift)
    R = radius of the lead screw


    This formula is based on the "law of the machine"

    The final effort amount with its unit of newtons and R will be the torque. For example, if the effort comes to 100 N (newtons) and the R is .5 inches, then you can assume that the effort is 50 N-in since it would take twice the effort to turn form the one inch mark from the center of the shaft.

    Example:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 13 = .08 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .08) x .2))
    Effort = 5 N + (90 N / (6.28 x 12.5 x .2))
    Effort = 5 N + (90 N / (15.7))
    Effort = 5 N + (5.73 N)
    Effort = 10.7 N = 2.4 lbs = 38.4 oz-in

    I am putting the oz-in on the end because the formula considers the distance from the center of the shaft to be one inch.

    Therefore, a 425 oz-in motor would be able to lift a 20.2 lb Router with its accompanying assembly. If the assembly and router is heavier, plug in the numbers and determine the effort required.

    With a bit of algebra, the formula can be rewritten to find the load:

    Load = (Effort - Sf) x (2 x pi x (R/p) x Se)

    Another formula that does not consider friction at all:

    Effort = (Load x p) / (2 x pi x R)

    Lets see if we get similar results:

    Effort = (20 lb x .08 inches) / (2 x 3.14 x 1)
    Effort = 1.6 / 6.28 = .255 lbs = 4.08 oz-in

    The results from both formulas appear to be very small because a 13 TPI screw will have enormous mechanical advantage.

    It is evident that the first formula that does consider friction that we are loosely estimating is far more conservative than the second formula. Either way, even the most conservative formula shows that the 425 oz-in motor will handle very large weights. If you are using a lead screw with only two turns per inch, .5 inch pitch, you can determine the requirements with the first formula.

    Example for a 10 TPI 5 start (2 turns per inch) lead screw:

    Load = 90 N (20.2 lbs)
    R = 1 inch since that is the length from the center of the shaft that the motor is rated
    p = 1 inch / 2 = .5 inches

    Effort = 5 N + (90 N / (2 x 3.14 x (1 / .5) x .2))
    Effort = 5 N + (90 N / (6.28 x 2 x .2))
    Effort = 5 N + (90 N / (2.512))
    Effort = 5 N + (35.83 N)
    Effort = 40.828 N = 9.18 lbs = 146.88 oz-in

  • MY QUESTION THAT KNOW CANCER CAN BE CAUSED WHEN OUR BODY EXPOSED TO DOSES OF 50 CGY OR HIGHER. WHAT DOES STAND FOR? DO EMIT?

    The term cGy (centigray) is a unit of absorbed dose of ionizing radiation such as x rays or gamma rays. Cell phones do not emit ionizing radiation. They emit nonionizing radiation, namely radiofrequency (RF) energy. Absorption of nonionizing radiation in the body is measured in terms of the specific absorption rate (SAR) in units of watts per kilogram. Both ionizing and nonionizing radiation are forms of electromagnetic energy. The difference is that ionizing radiation has sufficient energy per photon to cause ionization of molecules. Nonionizing radiation does not. It is the ionizing effect of ionizing radiation that has been linked to increased risk of cancer. For more information on cell phones and health check out a Medical College of Wisconsin website. For more information on ionizing versus nonionizing radiation check out a University of Michigan website. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory

  • WHAT ARE CURRENT RECOMMENDED IEEE EMF OCCUPATIONAL EXPOSURE LEVELS AND GUIDELINES FOR RADIO BASE STATION ANTENNAS?

    The following answer assumes "radio Base Station Antennas" refers to base stations used for personal wireless communications services such as cellular telephone, Personnel Communications Services (PCS), and Enhanced Specialized Mobile radio (ESMR). In the United States, the frequency band allocated for base stations used for personal wireless communications is 869-894 MHz for cellular service, 851-866 MHz for ESMR, and 1930-1990 MHz for PCS. The IEEE exposure limits (maximum permissible exposure—MPE) for occupational exposure (controlled environments where exposures may be incurred by persons who are aware of the potential for exposure) are frequency dependent and are expressed in terms of incident power density. The appropriate value to compare with the MPE is the incident power density averaged over the vertical cross-section of the human body. The occupational exposure limits are also time-averaged over any six-minute interval. The IEEE C95.1-1991 MPE values are shown in the table below:
    IEEE C95.1-1991 Maximum Permissible Exposure (MPE) Values
    Frequency Band Power Density
    General mw/cm2 W/cm2
    851-866 MHz f/300 mW/cm2 2.84-2.88 28.4-28.8
    869-894 MHz f/300 mW/cm2 2.90-2.98 29.0-29.8
    1930-1990 MHz f/300 mW/cm2 6.43-6.63 64.3-66.3
    NOTE: f is in MHz
    As indicated above, these values are for continuous exposure (t > 6 minutes) and are to be compared with the spatial average of the incident power density. all base stations used for personal wireless telecommunications services in the United States are required to comply with the FCC limits (as mandated by the Telecommunications Act of 1996). The FCC limits are based on a hybrid of the IEEE limits and the 1986 recommendations of the National Council on Radiation Protection and Measurements. The FCC MPEs are the same as the IEEE values for frequencies below 1500 MHz but are capped at 5 mW/cm2 (50 W/cm2) for frequencies greater than 1500 MHz.

    Both the FCC and IEEE MPEs for exposure of the public (uncontrolled environments) are one-fifth of the above values. As above, the value to compare with the MPE is the incident power density averaged over the vertical cross-section of the human body. The averaging time for the general public is 30 minutes. Thus, for transient exposures lasting six minutes or less, the MPEs for occupational exposure and exposure of the general public MPEs are the same. For cases of simultaneous exposure from antennas operating in different frequency bands, the ratio of the spatially averaged incident power density in each frequency band to the corresponding MPE for that band is determined and the sum of all such ratios must be less than unity in order to comply.

  • WHAT ARE SOME USEFUL MODIFICATIONS CAN APPLY TO THE BLACKTOOTH LASER CUTTER?

    Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

    Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

    Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

    Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

    Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

    To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

    A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.

  • WHAT SOFTWARE CAN BE USED WITH THE BLACKTOOTH LASER CUTTER?

    If you take the standard parallel cable BoB (Break Out Board), then you will need control software (Mach 3 or EMC2) and CAM software to make your G-Code (such as CamBam). Personally I use CamBam and Mach 3, they work beautifully but don't expect to turn them on and know how they work out of the box. Give yourself a few weeks to get familiar with the basics. CamBam is VERY powerful software for it's price. I'm surprised how much I keep learning on what I can do with it...I highly recommend it if you want as much control as possible.

    Mach 3 + CamBam as a bundle costs $310. EMC2 will give you a free replacement for Mach 3 and is exclusively for Linux.

    If you use the USB BoB, it will cost an extra $75 + $75 for the software. This is an all-in-one package so no need for Mach 3 or CamBam.

    For etching rasters (jpeg, bmp, tiff, non-vectors, photos), I highly recommend PicEngrave. It has been a labor of love for the past 9 years and John has done a wonderful job with it. It easily compares in quality compared to software that is in the $200-$300 range. John's software runs $40 and can be found here: http://picengrave.com/ (don't let the modest website fool you, this stuff can do amazing things). DotG and the Mach3 engrave plugin are two other options and instructions can be found on Dustans page in the gallery on buildyourcnc.com website.

  • THESE MACHINES ARE DANGEROUS, WHAT DO DO?

    These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

    With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

  • USING MACH3, MY MACHINE STOPS IN THE MIDDLE OF A PROJECT. HOW CAN IT BE STARTED AGAIN FROM POINT STOPPED?

    Dealing with a mid-stop cut via Mach3, you will have to be careful if it is intentionally or unintentional. If you desire to stop your machine while in the middle of a cut be sure to stop it when the machine is moving in an upward motion on the z-axis and the X/Y-axis are stationary. Then you can choose the point (G-code) where the machine was left off and click on the Run from here button on the Program Run screen (left hand side) right above the Reset button.
    (Make sure spindle/router is running before hand!)

    Now if the machine stops unintentionally, and was moving in either the X/Y-axis, then it will be difficult to run the machine from the original point dealing with the coordinates might have been lost due the the machine continuing motion but via Mach3 the machine has stopped.

    If this occurs to fight this issue before hand, is marking your home with the spindle/router to make a hole were your home is. Although moving it manually back to home the machine can be off by the smallest amount and could cause an inconsistent cut. If accuracy is something that can not be risked, then you can home the machine about a 1/4" or 1/2" down from the original home to start your cut on the same material but loosing that small piece.

    Additional Information:


    Additional Information:
    My typical go to solution is:

    - Note the current g-code line where the machine stopped.
    - If Mach3 errored and you cannot control the machine, Exit Mach3 - you may find that reset, stop does nothing to stop the spindle. When you exit mach3, the spindle will stop automatically.
    - Restart Mach3. The DRO (Digital Readout) should show the correct coordinates where the machine position was before exiting Mach3.
    - Scroll to the g-code line where the machine stopped. You may need to go a few lines prior to make sure you are not skipping any machining operations (which is why it is a good idea to learn the basics of g-code - don't worry, it's easy)
    - Click on the "Run from Here" button.
    - Mach3 will present you with a "Preparation Move" dialog box with the location that it will move to. If the coordinates shows a position that is into the material, make sure to specify a rapid height (clearance height) so the machine will move up first and then move to the location before moving down into the material. If the spindle is automatically controlled by Mach3, make sure to check the turn spindle on checkbox. If not, make sure the router or spindle is on before clicking OK.

    Additional Information:
    If you have a license for Mach3, then you should be able to run g-code indefinitely. I think there is something else going on.

  • wHAT IS THE SMALLEST LENGTH SHAFT I CAN USE FOR YOUR #25 DRIVE SPROCET?

    The hub length of the drive sprocket and the other mechanical devise that is used to connect on the shaft will determine the length of the shaft needed for use with the drive sprocket.

    The hub lengths for our drive sprockets are 1/2". So if you are connecting the drive sprocket to a motor, your motor shaft will need to be at least 1/2" in length.

  • FIRST OF ALL, THANKS FOR DESIGNING A WONDERFUL SITE. MY QUESTION IS: HOW DO YOU CALCULATE EME (ELECTROMAGNETIC EMISSIONS) AROUND THE TRANSMITTER (ANTENNA) AT ANY GIVEN POINT AND WHAT ARE MEASURES TO KEEP IT UNDER SAFETY CODE?

    Conceptually it is straightforward to predict the radiofrequency (RF) exposure intensity at any point in the vicinity of a cellular radio base station antenna. Simply multiply the effective radiation power times the inverse square of the distance times the relative gain of the antenna in the direction of the interest. The relative gain in different directions is know as the antenna radiation pattern and is usually available from the antenna manufacturer in graphical or tabular form.

    Unfortunately, in real life the calculations involved in base station antenna evaluations are quite complex and require expert knowledge and experience to deal with the many parameters that are involved. An excellent reference summarizing this process is the Federal Communications Commission OET Bulletin No. 65 titled "Evaluating Compliance With FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields," available on the Federal Communications Commission (FCC) website.

    To assess the RF hazards associated with handheld cell phones it is necessary to predict the rate of absorption in the body of radiofrequency energy, a parameter called the specific absorption rate (SAR). This is a very complex calculation, and cell phone manufacturers often rely on measurements of SAR in fluid-filled cylinders or plastic containers in the shape of a head. The FCC requires cell phone manufacturers to provide this data to FCC. You can obtain the data for your model phone on the the FCC's website. Unfortunately only cell phones manufactured in the last couple years are listed here.

    As to your question about keeping RF exposures within the safety code, please read the other questions posted on this website this matter. Cellular radio products that meet FCC requirements will be within the guidelines established by safety standards organizations for users' and public exposure to RF radiation fields.

  • ARE THERE PRODUCTS AVAILABLE TO THE GENERAL PUBLIC THAT CAN BE PURCHASED PROTECT CELLULAR OR PORTABLE TELEPHONE USERS FROM RADIATION? IF SO, WHERE THESE FOUND?

    There are a number of opportunistic gadgets on the market to allegedly protect the user from hazards of cellular phones. You can search the Internet to find the latest, ranging from antenna shields to whole-body shielding materials. Most experts believe that these devices take advantage of customers' misunderstanding and unfounded fears to sell products with no real value. First of all, cell phones that operate within the guidelines established by national and international safety panels have never been shown to pose a health risk to the user (see answers to other questions on cell phone safety on this website). Secondly, placing any kind of shield over the antenna of a cell phone will in most cases cause it to increase its RF output as it attempts to compensate for signal loss in the shield and maintain a quality phone call. The U.S. Food and Drug Administration published an advisory on cell phones several years ago that said if you are concerned about risks of using a cell phone, then simply use it less. That is still good advice today. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory

  • LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.

    BYCNC Response:
    This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

    User Response:
    I am using the cnc planet software for your USB board. Are the limit configurations in this software?

    BYCNC Response:
    Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

  • WHAT CAUSES RINGING IN YOUR EAR AND HOW CAN YOU STOP IT?

    Tinnitus . Learn to love it. No really you should see a doctor. Make sure. White noise will help you sleep when it gets loud.

    Additional Information:
    I learned, too late, that if a sudden loud event causes tinnitus, see an audiologist IMMEDIATELY. They can do something about it if addressed within a day or so.

    Wear hearing protection...always. Loud noises trigger my tinnitus, and headphones and ear plugs (when out & about or at the movies, subway, etc) help tremendously. Mine are rated 33dB.
