INTRODUCTION
CINCINNATI FM
The FM is a hydraulically driven press brake. Linear transducers (potentiometers)
constantly monitor the bed-to-ram position and are interfaced with the FM Multi-Axis
LCD Control. The control is a programmable microcomputer accessed by the operator
through a keyboard with an LCD display.
The FM Multi-Axis LCD Control can be programmed for a simple vertical stroke of the ram,
sequencing the ram to multiple depths, as well as vertical and horizontal movement of the
optional backgage. The Multi-Axis Control can be used for a quick, single-bend job or for a
complex multi-bend part. Once the program has been entered and run, it can be saved in
the control memory for future recall and use.
PART QUALITY
The following factors affect part quality:
✦ Press Brake condition and repeatability
✦ Operator ability
✦ Type and condition of tooling
✦ Quality of material
The FM is both rugged and precise; with reasonable maintenance and proper operation, it
will form metal parts easily and accurately.
Operator ability obviously affects part quality and production rate. CINCINNATI
INCORPORATED provides many design features in the machine and optional accessories
to aid the operator in producing consistent parts. The operator or setup person must
select the best tooling from those available. The type of gaging, material supports or
other special equipment will affect how the part is produced. Selecting the proper bend
sequence is important to obtain quality parts and for operator safety. CINCINNATI offers
both operator and maintenance training programs at our factory to address these
factors. This training may cover subjects such as the basics of forming and micro-
computer controls.
Tooling that is worn, damaged or of poor quality can directly affect part quality. Using good
tooling, selecting the correct tooling for the job, and setting them up properly is essential for
producing good part quality.
Quality of material can affect angular tolerances of the bend. This is due to normal
material thickness variations found in commercial steels as well as hard and soft spots
in the metal. Using a good grade of material and the proper tooling set-up will minimize
bend variations.
The contents of this manual will assist in understanding the operation, safe use and
maintenance of the CINCINNATI FM Hydraulic Press Brake. Read this manual before
operating the press brake.
