Doesnt look to be anything overly complicated. Simple 2D tool paths and a bit with enough reach to get the entire profile.

How big is the piece in the last picture, how wide and how long. It is not that difficult to run on a cnc, if it is not to long for your table, I would order tooling to match the radius on the piece, if it is a consistent radius. For Production depending on the size, a cnc is not the tool of choice in my mind, you need a moulding machine or a shaper. You may have to do multiple passes and no matter what you use you will have to get custom tooling made. A person would need to know the size to give you the best method for production.

The first pic is easy, just make sure you understand stepped cutting cause itís pretty deep/thin in middle cutout for hardwood. The second pic is not worth doing on cnc unless have too. Order that standard cove style crown from a supplier in any species you want, they are tooled up for it with moulders.

Yes you can use Aspire for all of this, Yest on Moulding it is far far less expensive to have it run if you need any large quantity.
If you need a few feet then it can be done with a large ballnose and a 3d path.

I did both of these files in less than 10 minutes, ready to cut the legs with say less than 6 min per leg

the mould is a 3d file and with a BIG 1-2" Ballnose may not take too long if you do not need 500 feet

Wow James, you are a machine. I am sorry to hijack the thread, but what part of aspire would you use/require with just a 3 axis nesting machine. I guess I am asking what would you use it for? I looked online and it is broken down into a bunch of different parts, do you need the highest level or only say the vcarve pro part?
thanks

We would machine both of these in Vcarve easily. 2D toolpaths for the bracketry and unlike James post (which is most definitely fine) we would use a molding toolpath for the cove molding.

We do a lot of small run reproduction molding on the CNC. Jobs where the customer needs 3' of a given profile, or 10' of a piece of base. Without a doubt there is a breakoff point where running the part on the molder is better. Thats easily calculated by the cost of custom knives, setup, and so on. For us, its usually about 30' depending on the profile. It simply doesnt pay to have a set of knives ground and the setup to run 30' of molding.

Using a 2 rail sweep in the the molding option in Vcarve you can run any of these profiles with simple ball nose or other form tools. There is a little handwork at the end for cleanup and if its a high dollar job grinding the knives is still the way to go but most often for a short run the CNC does fine.

Sorry I was fixing Golf carts (Farm animal feeders)

V carve Pro has a lot of features added since it was my primary software (2008) I have used only Aspire since then, the corbel is a 2 d file, I did the molding with a 2 rail sweep.

  • 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.

  • 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.

    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.
