Solid wood nesting tooling

Hello, all!

We have recently acquired a Homag N-500 nesting cell. We plan to machine kitchen cabinet parts from 8' x 4' x 3/4" or 20 mm sheets of solid yellow pine. I've talked to the sales reps of Leuco, AKE & Leitz but they really don't know what tool to use for this.

I'm thinking 1/2" solid coated tungsten with an upspiral.

Anyone with experience from this?

Best regards,

FS Tools has an chipbreaker spiral solid carbide cutter recommended for softwoods and fast feedrate. Don't underestimate the ability of brazed straight flute carbide bits. This is what I use to cut out 1 1/2" thick pine parts on a vacuum fixture. I do a final full depth pass at .015" to finish the cut and get reasonable surface finish with only occasional break out at short grain corners.

I think a 3/8" bit would probably do the job for you. Less stress on the machine, lower amount of chips and faster feed rates. At least give it a try.

Using an up spiral bit will depend on the ability of the vacuum to hold your work. If your pieces are small, the lifting action of the spiral will pull them off the table. You can use some toolpath strategies to help like a last pass at 1mm depth of cut and step over of .5mm. But you sacrifice speed.

I can't imagine a 4X8 solid wood panel being consistently flat enough for nested CNC's.

Also, what about blow out in the corners?

Solid wood is a completely different animal than any kind of sheet goods or even plywood.

Up spiral bits can tear it pretty badly even with the grain, especially soft wood like pine. I'd look at chipbreaker compression spirals. You may need both left and right spirals to deal with the aforementioned corners.

When cutting wood or composite wood materials, the damage of welded carbide milling cutters is often not due to tooth wear, but due to the disadvantages of high temperature welding or grinding heat during sharpening

Use a roughing bit hole cutting the parts slightly oversized. Vortex makes a nice 1/2 " roughing bit .

Then do a final pass with a sharp down spiral or straight flute taking off the final 0.01 or so .

Climb cut , and the corners on the right top and esp bottom of the parts may still chop out a bit .

Solid wood is not the easiest to machine on a router

HOLZ-HER's nesting technology ensures efficient formatting and drilling on one machine. Here the panel is held by large-surface vacuum on a wear plate. The great advantage of this production method is production of exactly formatted workpieces, already provided with groove or rebate in the rear wall and all required vertical holes for shelves, connectors, etc.for the wood guide info woodyman https://woodymanreviews.com is the best i do use for wood guide and Above all the entire process is accomplished without additional handling work and is therefore extremely efficient in terms of time and resources.

  • 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.

  • 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.
