Case Study

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 ½ 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 ½ 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.”
