Question #: 13510

Question: Does Bobcad do CAM for lathe? Others are saying that Fusion360 free edition has better more efficient toolpaths. how does Bobcad compare to free Fusion360?

Current Solution

BobCAD does have a program specifically for lathe.

I would have to agree with the others, but more on the user interface rather than the tool paths. I haven't studied the tool paths to any extent to provide a comprehensive response, other than Fusion360 (AutoDesk) has a far more advanced and cutting edge track ahead of it.

Tool paths for lathe are relatively simple (depending on the machine and number of tools you are using), so I can't imagine that the tool paths are much different.

  • 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

  • WE'RE GLAD THAT CDC HAS MADE A UNIVERSAL INFLUENZA VACCINATION RECOMMENDATION TO VACCINATE EVERYONE 6 MONTHS AND OLDER. WOULD YOU TELL US HOW THIS CAME ABOUT?

    Prior to the 2010-11 vaccination season, only children ages 6 months through 18 years and adults age 50 years and older were universally recommended for vaccination; recommendations for adults ages 19 through 49 years were targeted to people with specific risk factors, although other adults could be vaccinated if they wanted protection. Collectively, these targeted risk groups made up 85% of the U.S. population. During the 2009 H1N1 outbreak, additional risk groups were identified, such as obese individuals. The recommendation made by ACIP in February 2010 for universal vaccination simplifies previous recommendations, making it easier for healthcare providers to determine whom to vaccinate. The universal recommendation also makes it easier for patients to remember to get vaccinated every year.

  • AM NOT SURE HOW TO SET THE Z AXIS TURN ON/OFF LASER WHEN CREATE CODE. KNOW THAT ITS TYPICALLY Z-AXIS MOVEMENT DOES THIS - BUT YOU DONT SHOW ANYTHING HOOKED UP IN PLACE OF AXIS.

    When the z axis is going down, the laser turns on. When the z axis is going up, it turns off. The z axis directions is only a signal that is either 5v or 0v. That determines the direction. In vectric, you will need to set your machining operations with a very very small depth so the time it takes to get to its final depth is a very short time.

  • WE'VE HEARD THAT ACIP HAS LIMITED THE USE OF ONE INFLUENZA VACCINE PRODUCTS FOR CHILDREN BEGINNING WITH 2010-11 VACCINATION SEASON. TRUE?

    Yes. You are referring to Afluria, which is manufactured in Australia by CSL Laboratories for the U.S. market. CSL's 2010 Southern Hemisphere influenza vaccine (Fluvax and Fluvax Junior) has been associated with increased post-marketing reports of fever and febrile seizures in children predominantly younger than age 5 years as compared to previous years. For this reason, on August 5, 2010, ACIP recommended that Afluria, 0.5 mL, licensed for use in people age 36 months and older, not be used in children younger than age 9 years. ACIP further recommended that Afluria could be administered to children ages 5 through 8 years who are at high risk for influenza complications if there is no other age-appropriate TIV available, after risks and benefits of using this vaccine in this age group have been discussed with the parent or guardian. The vaccine should not be given to children younger than age 5 years. For detailed information, go to www.cdc.gov/media/pressrel/2010/s100806.htm.

  • WE ARE ALWAYS CONCERNED THAT THERE WON'T BE ENOUGH VACCINE TO VACCINATE OUR PATIENTS IN THE FALL. WHAT CAN DO ASSURED WE'VE DONE ALL POSSIBLY AVOID THIS TYPE OF SITUATION?

    It is never too early to begin planning for the coming fall's influenza vaccination program. The most important thing you can do initially is to place your order for vaccine from your usual source. Some manufacturers often stop taking pre-orders in mid-May. Be sure to include vaccine for pediatric patients needing two doses and also for your facility's healthcare workers as part of your overall campaign.

  • THE ROOM HAS THICK CONCRETE WALLS PLUS LEAD SHEETS. LEVELS OF EXPOSURE I AM GETTING WITH LUDLUM MODEL 3 SURVEY METER (SM) A 44-9 PROBE ARE BETWEEN 0.1-3 MR/H IN WORST CASE (HIGHER ENERGY AND POINTING BEAM TO WALL). SM WAS CALIBRATED 137CS MY NOMINAL 18 MV (MEAN ~5 MV). WHAT KIND INSTRUMENT MORE ADEQUATE USE FOR THIS TYPE BETTER RESPONSE?

    Pulsed radiation fields are encountered in the vicinity of electron Linacs (McCall and Ipe 1988). Most therapy Linacs are operated at repetition rates varying from 100 to 400 pulses per second with pulse widths of about 1 to 10 microseconds (AAPM 1986). The fraction of operating time (that is, pulse width x repetition rate) during which the beam is on is called the duty factor. For example, the duty factor for an electron Linac operating at 100 pulses per second with a pulse width of 10 µs is 0.001. These small duty factors impose severe limitations on the radiation detection instruments. The peak intensity is equal to the average intensity divided by the duty factor, which in this case will be 1,000 times higher than the average intensity. An instrument that normally responds well to the average dose rate spread out evenly in time will not be able to cope with such a high dose rate. The intense photon pulse usually overwhelms any active detector (that detects particle events electronically). Instruments which have long dead times, such as the GM and proportional counters, tend to become saturated in such fields and only count the repetition rate. Thus GM counters should not be used to perform radiation surveys outside exterior walls of the Linac room. Scintillation survey meters may become nonlinear at higher dose rates because photomultipliers cannot handle the high instantaneous currents.Ionization chambers are less influenced; however they must be operated with adequate voltage to overcome recombination losses. There are several commercially available ionization chambers that can be used for Linac radiation surveys

  • HOW CAN I DETERMINE THE DOSE EQUIVALENT (MREM/HR, MREM/WK, MREM/YR) USING RAW DATA FROM A TLD (THERMOLUMINESCENT DOSIMETER) THAT WAS PLACED IN AN OFFICE FOR 22 DAYS?

    Assumption 1: The "raw data" of 24 mrem on the TLD is the total dose received by the TLD during the 22 days that the TLD was deployed in your office. This means that (1) any TLD reader background signal has been properly subtracted, (2) the signal accumulating in the TLD during any transport or storage time between preparation (annealing) and deployment in your office has been properly subtracted and, (3) the signal accumulating in the TLD during any transport or storage time between removal from your office and processing (reading) has been properly subtracted.

    With this assumption, the total dose rate in your office is (24 mrem)/(22 days), or 1.091 mrem per day. The reference background is given as 63 mrem per year which is (63 days)/(365.25 days per year) or 0.172 mrem per day. Thus the average net dose rate to the TLD during the 22 days was (1.091-0.172) = 0.919 mrem per day.

    Assumption 2: The net dose rate of 0.919 mrem per day in your office is attributable to the accelerator or other regulated sources under the control of your institution.

    Assumption 3: The office occupancy factor of 1/4 attributed in your question to NCRP Report 49 was misread from Table 4. The correct occupancy factor given in NCRP 49 for offices is 1.

    Assumption 4: You take 20 business days per year off for vacation and holidays. You work in your office for the remaining 240 days per year.

    Assumption 5: All of the accelerator shots occur while you are in your office.

    Assumption 6: The average net dose rate of 0.919 mrem per day determined during the 22 days of measurement continues for a year.

    Based on the data that you provided and my assumptions, your annual dose received in your office from the accelerator or other regulated sources at your institution is predicted to be (0.919 mrem per day) x (240 work days per year) = 220 mrem.

  • BUT DIDN'T SEE ANYTHING ABOUT COOLING THE LASER OFF - IS YOUR SETUP LIKE MOST OTHERS NEED BUCKET OF DISTILLED WATER TO PUMP THROUGH MACHINE?

    Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

    1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

    2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

    3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.

  • 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

    Yes, that is highly recommended for all the reasons you can imagine. Say you were doing engraving, not surfacing the spoilboard will either exhibit some areas that have no engraving at all, or areas that have engraving that is too deep. If you are cutting completely through the material, then one end may be cut all the way through but the other end will not have a complete cut, or produce onion skinning on the bottom of the workpiece.

  • COULD YOU PLEASE EXPLAIN, IF IT'S TRUE, THAT HANDS-FREE CELL PHONE CAR MICROPHONES RADIATE MORE THAN ANY OTHER INSTRUMENT USED WITH THESE PHONES?

    Hands-free cell phone car microphones have been tested by the manufacturers and meet the current ANSI/IEEE (American National Standards Institute/Institute of Electrical and Electronics Engineers) standards for radiofrequency (RF) safety. These are the same standards that the Federal Communications Commission enforces under the Telecommunications Act of 1996, and they place limits on the specific absorption rate (SAR) of RF energy in the body. Recent inflammatory articles in the British press were not substantiated by testing at ISO-accredited testing facilities at Motorola. Manufacturers of cell phones are required under FCC regulations to assure that their products meet the SAR limits on both hand-held and hands-free units. Further information can be obtained on the Internet at The Center for Devices and Radiological Health (FDA information) or Office of Engineering and Technology (FCC information).
