CNC Vector speed

4/26/15

In contemplating cnc machines will a 100m/min vector speed vs. 68m/min have a material effect over a years production?

100m/min is really flying, a typical cut is way slower, in the neighborhood of 10, 20 or 30 m/min for one two or 3 flute tools respectively at around 18Krpm. So by vector speed you must be referring to no load rapid travel. This is most often used in going from park to start, finish back to park between cuts and the bigger one, tool changes.
If so, then it depends on how much production you do in a day, what your tool strategy is, what type of tool changer you have (static or ride along) and how often you change tools.
Nearly all shops who operate CNCs run the machine sporadically, myself included. Anywhere from 5 to 25 hours per week on average I run 20 typically in a pretty busy commercial shop. The total times added for a slightly slower but still pretty fast (68m/minute is still way faster than a typical cut) is negligible for me and most people. You might be able to shave 20 seconds off an 8 to 12 minute sheet with a faster rapid if you have a static tool rack. If the tools travel with the head, even less.
I think this all speaks to the robustness of the drives more than a real time issue. If you are a really high volume production shop, maybe it is an issue, but a lot more comes into it at that point.

Thanks for your response Mark. A little more info. We run parts on the CNC, it's not a nested machine. We are also higher volume, running the machine around 35-40 hours a week with anticipation of even increasing the hours in the near future. I realize the vector speed is the no load travel speed and just wondering over the course of a year if the difference in the vector speed will add up like throwing change in a jar or if it is really negligable.
Thanks for any response

If you are running that much, It is worth doing a time study to see just what kind of benefit you are looking at. I nest myself, so I have less of a gut feel for your situation, but likely a setup like yours does fewer tool changes but does a home run for each part. Perhaps you can figure your total distance traveled per typical part cycle and use 100m/minute to gauge your rapid time per cycle? This ignores acceleration of course, but it is a place to start. Do you pendulum process or load while idle? how many cycles per day?

If a cycle with loading took X seconds and you gain 1 second per part......Lots to think about. I doubt it would be the most important factor in choosing a new machine, but not irrelevant either.

Thanks for your response Mark. Your last line hits the mark. "Not the most important factor, but not irrelevant either"
I have more studying to do.

Does anyone have any more accurate data on this? Say for an "average" sheet of cabinet parts for frameless MDF with blind dado, shelf/hinge and pilot holes.
We are comparing nesting machines, SCM Pratix S18 (35m/min vector) and Biesse Rover A (100m/min vector), both with static tool holders and 12 tool drill blocks.
Of course the SCM salesperson tells me it won't make any difference but I don't want to find that we are waiting on the machine during busy periods.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
