CNC Wood Machining - Windows
Among the most demanding jobs of an architect or designer are the creative decisions involved in a particular project's windows and doors; for a home, these elements provide both separation and union with the world outside. They must both close out and protect, as well as make possible the entrance of light and a view of the outside world. Aside from the demands associated with the performance of these elements for permeability to air, water tightness and resistance to wind-load, today's builder and home owner are looking for "cutting edge solutions", which are aesthetically and architecturally at a high level, including the capacity for special requests such as arched sliding windows, curves in place, non-square and so forth.
- Pro Evolution
CMS' ground breaking work in the re-industrialization of this market is represented in its most recent generation of CNC controlled window and door production systems - the Pro Evolution series, used for the complete machining of each window, or door, component: all edges, according to order, just-in-time, by-the-batch, ready to assemble, with machining for hardware, efficient high capacity production, automatic changing between various tooling families and part thicknesses without setup or downtime, flow though, verification of raw component size prior to production to ensure its correspondence with the requirement, automatic downloading of information for all processes for each component at the point of production, and much, much more.
Yet in addition to its newest technology, Pro Evolution, CMS solutions for window and door manufacturers have been specifically developed over many years and continue to provide a wide range of standard and special CNC machining capabilities for each specific manufacturer's need from traditional CNC machines to highly automated production systems.
ARES - all around CNC machining, including window components
ARES, CMS' moving bridge class machining center, with its all around CNC machining capabilities and powerful 5-axis working unit, type PX5, when equipped with CMS' pod and rail system, as shown in this photo, carries out production level demands for stile and rail components, as well as doing it with pendular work cycle capability and easy adaptability for special requirements with its extra large 3D work envelop.
AVANT Domus model - flexible all around machining for windowsAVANT Domus model, CMS' moving gantry class CNC machining center, is perfectly suited for producing a window manufacturer's wide range of components, including special requirements and at a batch demand production level. Avant Domus is equipped with CMS' unique CNC controlled pod and rail system, making it possible for Avant to accept the setup commands necessary to set all its rails, holding pods and reference stops to specific locations, even in a pendular production mode. In addition, Avant's pod and rail system uses CMS' modular pod components, meaning that they're easily changed out with each other and there's a wide variety of types to use depending upon the need, including: vacuum pods of various sizes and shapes, vices, and clamps, all under CNC control. Avant's pendular work capability also makes it possible to machine rail and stile components on one end, as in the photo to the bottom right, while on the other end to machine the assembled frames from already produced components - or to machine more stile and rail parts in a pendular work cycle - as in the photo to the bottom left.
Avant Domus is equipped with 2 independently CNC controlled powerful working units, type TX3, to mask tool changing time, so that one unit can be working while the other is changing out a tool, and which can select from a wide stock of cutting tools including: heavy profile cutters, counter-profile cutters, both left and right handed to eliminate blow-out at the ends of the rail, 4th axis aggregates for sawing and horizontal drilling, and more. Avant's dust collection system combined with its chip and scrap take away belt system at the bottom, means Avant does a heavy work, while keeping the work area clean.
In the bottom right photo, Avant is shown holding a rail for a window frame, with the use of 3 of its CNC controlled clamping devices, and has completed the tenon and mortise machining operations for the ends and one long side, which can now be assembled with other already finished stile and rails parts into a frame ready to be machined on the outside edges. The work for the arch sections is easily carried out in the same manner, and Avant can also be programmed so that multiple parts can be held in its clamps, resulting in groups of parts ready to be assembled, which can be unloaded at the end of each machining cycle.
In the bottom left photo, Avant is shown holding and preparing to machine the now assembled arched window frame. Avant presets under CNC control its reference stops and clamping pods along the reference sides, the operator then lays the frame in place, at which point Avant moves its remaining clamps to the opposite inner sides and clamps the frame securely in place, at which point the machining cycle is ready to begin.

Pro Evolution - high level automation features
Pro Evolution's remarkable productivity and automation exploits CMS' most recent patented concepts in engineering and the power of information technology.
The upper left photo shows CMS' use of barcode scanning to download automatically all the information for a particular part from the customer's information management system. The information contains the relevant characteristics of the part and its dimensions, which are interpreted, the necessary code generated and distributed to the various work areas in Pro Evolution for execution.
The upper right photo shows CMS' patented CNC controlled clamping system for holding and moving each component through the work cycle. The clamping system also securely holds each part until it has been clamped by the next set of clamping devices, meaning each component's accuracy is assured. CMS' patented clamping devices also permit working with short or long parts, or holding 2 parts during the same machining cycle for more productivity, and in addition they're pressure calibrated for various materials to avoid surface marking.
The lower left photo shows CMS' patented glazing bead machining group, which not only mills the bead profile and trims it free from the component as it's being processed, but re-attaches it at the same time during the process, so that it stays with the part, for when its needed later.
The lower right photo shows Pro Evolution using a laser marking device to mark parts that have finished the processing cycle as they leave Pro Evolution, so that they can be identified later as to part number, date of production, time and so forth, as well as placing the mark in an inconspicuous area.
Pro Evolution's unique capabilities push high quality, extremely accurate, order by order production demand components through the manufacturing process and distribute real time information throughout the manufacturing system as needed, including its ability to remotely message its own status to key personnel by email or text message, so that everyone's in the loop and things keep running smoothly.

Wood Windows: Case History and Technology Overview
Window manufacturer, Albertini, and its broad line of beautiful, functional and personalized window and window wall products is featured in this CMS case history on one of Europe's leading window and sliding door manufacturers. Albertini does it all: curved windows, arched windows, window walls, standard windows, customized and personalized window designs, and this case history includes a quick look at its production floor, as well.
CMS' window technology overview covers its broad line of CNC machining centers specially adapted and directed toward the needs of window manufacturers including a look at: Profiler, CMS' CNC machining center technology for rebating and hardware machining for assembled windows, as well as doors; Pentax with CNC controlled pod and rail system; Avant Domus with CNC controlled pod and rail system, and its capability for machining assembled unique shaped windows as well as making their components; and CMS' newest technology, a fundamental re-industrialization for window component manufacturing, Pro Evolution 1 and 2.
Throughout the review is featured CMS' processing technology capabilities such as: heavy counter-profiling of the stile and rail ends without "blowout" and without the use of "left-handed" versions to avoid "blowout", heavy profiling, drilling and machining for hardware requirements, 4th axis saws, 4th axis gang drilling, automatic machining and re-attaching of the glazing bead, and a good look at Pro Evolution's concurrent processing capabilities and patented CNC controlled clamping devices and how they had off their work to one another, assuring the maximum accuracy, as well as seeing how its all done in the manufacturing of arched components, custom components, as well as prefinished stiles and rails ready for assembly.
Avant Domus - Arched window, machining components and assembled window
CMS' Avant Domus produces all the parts for an arched window, including its stiles, bottom rail, arched top rail and interior rail and finishes with the machining of the assembled arched window. Avant Domus executes its program to automatically setup all of its rail, pod, and reference locations, the operator loads the parts to be machined and Avant carries out the processing operations including the heavy counter profile on the ends, the heavy profile along the side, along with 4th axis saw blade cuts on the ends and horizontal drilling on each of the parts. Following completion of the work on the individual parts, they're assembled and return to Avant for rebating and hardware machining. Avant again executes its setup program for positioning the reference stops along the bottom and side of the part, along with the clamps as well, when the operator places the frame against the stops, he initiates the program continuation and the clamps activate and hold the bottom and side securely and move the other clamps to the opposite end and side, lock in place, and begin the machining cycle for rebating and hardware operations.
Window component machining
One of CMS' CNCs is shown machining the components for a chordal arch window. As with CMS' Avant Domus—and available on other CMS models—it is equipped with CMS' CNC controlled rail and pod system, and uses it in this case, with a "hold and hand off" methodology, so that the machining for the arched top rail can be completed on all sides, using one set of CNC controlled clamps to hand off the part to another, ensuring that the part is always securely held. In the first part of its machining cycle, the system clamps the arched rail from the inside and carries out the end and side machining, following which the hand off takes place, the part is held from the outside, and, in the final part of the cycle, the system completes the machining for the inside of the arched top rail. Finally, the system carries out all the remaining machining processes on a pair of stiles, including the glazing bead.
