CNC Machining - Marine Wood Furniture
Boatbuilders need the same fundamental capabilities of good woodworking technology as those in the general furniture and woodworking industry.
For more information on panel "nesting" technology and its application, which also serves marine case-goods production well, please see "Wood - Nesting" located within the "Building" sector, where the fundamentals of nesting are covered.
Karat - working in a cell and feeding a line, nested based machining
Karat, CMS' moving table class CNC machining center, is working here, in addition to standard thickness sheet material, with thinner material and being held with a vacuum waste board. The sheets are automatically fed from pre-staged stacks and loaded on each of Karat's moving tables, when ready. After the machining cycle is finished, the sheet, complete with all its parts, is moved as a group with a special high density vacuum outfeed device to a take away belt, which feeds the down stream production line. After the sheet has been removed from Karat's table, a scraping and cleaning device removes any debris from the working table, leaving it ready to receive the next sheet to be machined, a highly efficient system for handling panel part production.
AVANT - Inline, flow through, belt version
Panel parts of all sorts are required for interior boatbuilding cabinetry. AVANT, CMS' moving gantry class CNC machining center, makes it possible to work with a wide range of panel sizes, without the use of waste boards, special fixtures or traditional manual machining methods, while providing the benefits of improved yield, part management, and labor efficiency. Even panel parts used in high quality, decorative flat panel, foil covered doors, with intricate profile designs carved into the surface, are easy work with Avant's vacuum belt system, providing secure holding and automated panel movement through the system without operator assistance. In fact, Avant's flow through design means it can handle a variety of work, in which Avant receives flat panels and machines them into completed components ready to be used at another point in manufacturing, to which Avant can feed the entire sheet, with completed panel parts, ready to be separated and sent on to the next operation.
For additional information regarding the technical manner in which Avant holds entire sheets with its belt, the cutting process involved and machine capabilities, please refer to the "Wood Nesting" sector.
Avant - flow through belt with integrated infeed system and unloading area
Avant, as opposed to working in-line, can also be equipped to work as a manufacturing cell, in which case Avant is provided with an automatic infeed system, capable of working from stacks of material of various thickness and color, all predetermined and all the various information, related to the specific work to be carried out for each individual sheet, available to Avant via a barcode label read on the top of the stack before it processes the first sheet. Avant can also apply production labels for each part that will be machined from the panel, making it possible to track the parts after they're separated from the sheet. After Avant has completed its work, in this version, Avant moves the sheet forward on its extended belt so that parts can be removed, stacked and moved to the next manufacturing process.
For additional information regarding Avant working with an infeed system and unloading area, please refer to the "Wood Nesting" sector.
Nesting - panels, frames, true shape and laser ID
Panel nesting methodology offers a range of opportunities for improved material yields, reduced labor, consolidating parts within orders or across orders - when additional freedom of the batch window is flexible, feasibility of carrying out technically challenging work, and even the addition a part ID.
The photo shows a fully nested sheet of MDF doors with "water fall" edge profile, high concentration of different sized parts, with part rotation and nesting of various sizes to obtain the best yield. In addition the sheet has received machining to obtain some panel frame parts, the photo to the lower left shows a part edge with laser marking for part identification and tracking. The photo to the lower right shows a group of parts derived from "true shape" nesting, in which it's possible to recognize the edge of the part and move it as closely as possible to another to obtain the best yield.
Nested sheets, roller hold technology & multiple working units
Avant's flow through vacuum belt system can also be equipped with CMS' special roller holddown technology, in which it's possible to stack sheets on top of each other, which have identical part layouts, and carry out the machining on 2 or more sheets at the same time. CMS' unique roller holddown system maintains contact with the sheet stack constantly throughout the cycle, applying pressure to the stack and ensuring that the sheets do not slide over each other. In addition, Avant's roller holddown system is flexible, maintaining a close relationship of the rollers when routing, and adjusting the interaxis between them to accommodate for other working units. CMS' roller holddown technology also has the advantage that sheets with some warp in them are nonetheless held throughout the cycle, ensuring good results where otherwise holding such a sheet would be difficult or impossible. Avant can also be equipped with multiple routing, drilling, or 4th axis sawing units, working at the same time, and independently adjusted in their relationship to each other to improve its productivity even more.
Additional equipment - labeling, profile floating, vacuum unloading full cut sheets
Production requirements vary, but CMS provides a wide range of additional, optional, equipment for handling each need, as for example:
• the photo to the upper left shows a labeling device, which may be used either at the infeed area to mask labeling time during the machining cycle time, or used within the machining cycle itself, average time to print and apply a label is about 3 seconds.
• the photo to the upper right shows a laser burning device to ID parts prior to finishing the machining cycle, the laser mark may be placed on the surface or even the part edge while still in a nested layout.
• the photo to the lower left shows one of CMS' unique floating devices, which makes it possible to precisely machine profiles, even complex groups of profiles, which need to match up to one another, as in the case of MDF cabinet doors, resulting in profiles that all match up, being at the same expected depth from the surface, even if the panel thickness varies. the photo to the lower right shows a special CMS vacuum unloading device, which is capable of unloading an entire sheet of parts, regardless of varying part placement within the sheet or from sheet to sheet or having small part dimensions.
CMS recognizes complete technological solutions are essential, and has provided an ever increasing range of solutions for its customers' requirements.

Panel nesting: Case History and Technology Overview
Panel nesting technology is reviewed in the case study of Groupe Lacasse, premier case goods office furniture manufacturer. In addition, CMS presents its extensive range of CNC machining center, nested based panel production solutions, with waste board vacuum holddown or CMS' exclusive vacuum belt system, either inline or stand-alone, systems with manual or automatic loading or unloading, with a look at CMS' special roller hold-down technology, floating heads, saw blades, labeling, laser marking, high speed routing and much more.
Avant - nested furniture panels with system 32
Avant, with CMS' flow through vacuum belt, is shown machining furniture parts from nested panels, the parts are engineered using system 32 assembly methodology. Avant brings the panels to be worked into the machining area, aligns them, vacuum's them securely in place and begins the high speed drilling operations for the many holes required for the parts, following which it carries out the routing of the parts. The time for changing tools for the routing cycle was "masked" and took place during the drilling sequence to optimize cycle efficiency. Although the parts are regularly shaped and easily laid out for nesting, they could just as well have been irregularly shaped and optimized in a "true shape" nesting fashion for the many different interior shapes required in a yacht.
Avant - nested cabinet parts with laser ID marking
Avant is shown machining a batch of nested cabinet parts from an MDF sheet. The parts have a waterfall profile edge and Avant carries out this part of the cycle while using CMS' exclusive floating head to assure that the profile is at the correct depth from the surface, regardless of what may be the varying thickness of the panel. In addition, after the complete machining of the nest, Avant carries our a laser marking cycle in which identification information is placed on the edges of the parts, even while they are still in the nest.
