    RALU di Rabuffetti Ezio & C. s.n.c.

    Highlights RALU, based in Carnago, Italy manufactures stainless steel indoor and outdoor furniture as well as providing sheetmetal

    subcontract services. They have been

    using JETCAM with a succession of

    Power punch presses since 1997. In

    2010 they decided to purchase a

    Trumpf TCL3030 laser and started to

    evaluate software to drive it.

    Managing Director Angelo Rabuffetti

    commented; We investigated three

    systems. Despite running an old release

    of JETCAM we could see that it was still

    better than the newer systems. It also

    had the strongest laser support. Marco

    Quadrelli, programmer added; We

    explored the other systems deeply and

    found that it was still easier to create

    orders, split them by material and

    thickness and to make nests.

    The decision was made in June 2010 to

    upgrade to the latest release of

    JETCAM, added High Performance

    Rectangular and Free Form nesting,

    c o n v e r t i n g t h e l i c e n s e s f r o m

    standalone to floating and adding a

    postprocessor for the new Trumpf

    machine. An engineer spent two days

    o n - s i te u p g ra d i n g t h e syste m ,

    configuring it for the Trumpf and

    providing training for the staff. They

    also used SCAP (Single Component

    A u t o m a t i c P r o c e s s i n g ) t o

    automatically apply a layer of profiling

    information to all existing geometry

    files, making them immediately

    available for the new machine.

    JETCAM Orders Controller (JOC) was

    also installed to provide easy creation

    of order lists.

    Although RALU had used JETCAM for

    a number of years they were surprised

    by the number of benefits that the

    new version delivered. Logic had been

    improved on the Right Angle Shear

    module, which halved the time

    required to program for it. Tool teach

    mode reduced programming time by

    60% for the punch, with the system

    learning preferred tooling for specific

    cutting routines. Material utilisation

    also saw considerable and immediate

    benefits. Remnant sheet management

    Significant savings made through simply updating existing software

    60% improvement in programming time due to features such as tool teach and improved RAS

    15-20% improvement in rectangular nest efficiency

    Order lists that took 1 hours to create now take a few minutes

    Using SCAP all existing files were immediately available for the new laser machine

    Remnant sheet management saving even more material

    Two days to upgrade and train for the new laser technology

    Floating license

  • allows RALU to create a database of partially used

    sheets and intelligently recommend which sheets

    to use for each job, where previously these

    remnants would have been thrown away. The high

    performance nesting modules also reduce waste

    and material sheet changes, with Marco citing a

    15-20% improvement on their existing punch part

    nest efficiency; JETCAM generates nests that I

    was not able to produce manually. On one

    particular order I managed to get all parts on a

    single nest, which previously was impossible.

    The inclusion of JOC provided an easy interface to

    build lists of orders for parts or complete

    assemblies for each machine, separated by

    material and thickness. New parts or complete kits

    can be ordered by simply right clicking and

    specifying the required quantity. This information

    is then synced with JETCAM and ready for nesting.

    Order lists that would previously taken 1 hours

    now take around 10 minutes.

    RALU is working on expanding its sales network

    both in and outside of Italy. They plan to share

    capacity with other manufacturing partners that

    also use JETCAM to ensure that they all benefit

    from the material savings and a common

    geometry format. Angelo finalised; Implementing

    CAM software is something a company has to do,

    but JETCAM adds a real nett value to our

    production. In just one month we have seen

    massive savings, and we feel that this will only

    improve over time.
