1. Automatic Operation
This chapter explains the automatic operation and step operation of the
FCP IV-3.
1.1 Automatic Nozzle Selection
The FCP IV-3 features a function to automatically select the nozzle which
best suits a given part. The user defines the diameters of the nozzles and
nozzle background disks used by the program ([Program] Machine_data)
as well as the maximum nozzle diameter and minimum background disk
size permitted in placing the part. If a part must be placed by a nozzle of
a specific diameter, this is also input.
Based on this data, the FCP IV-3 judges which nozzle should be used to
place the part.
Data is input in two places: in the program and in the part’s Part Data file.
1.1.1 Program Nozzle Diameters
The FCP IV-3 holds three nozzle sizes per holder: S, M, and L. The
nozzle diameter assigned to each size could vary according to the
user’s application and thus may differ among production
programs. Accordingly, each production program defines the
diameter for each nozzle size in the following fields in
“Prog_information”.
[Program] Machine_data
38. S_nozzle_size:
39. M_nozzle_size:
40. L_nozzle_size:

1.1.2 Nozzle Reflective Disk Diameter Data (Program)
The diameter of each nozzle’s reflective disk is input into program
data to facilitate production.
[Program] Machine_data
42. S_back_light_size: Input the diameter of the reflective disk
for the S nozzle in 1 mm increments.
Default is 12 mm.
43. M_back_light_size: Input the diameter of the reflective disk
for the M nozzle in 1 mm increments.
Default is 12 mm.
44. L_back_light_size: Input the diameter of the reflective disk
for the L nozzle in 1 mm increments.
Default is 25 mm.
1.1.3 Part Data Nozzle Diameters
There are two fields in Part Data which are used in the automatic
selection routine of the FCP IV-3. They appear under
Carrying_data, as follows.
[Part data] Carrying_data
17. Nozzle_size_max. :
19. Nozzle_size_CP4 :
Since each part has its own Part Data file, data input here is specific
to the part that the file describes. Nozzle_size_max. defines the
maximum diameter of the nozzle which can be used in placing the
part. This is referenced by the FCP IV-3 during automatic nozzle
selection.
Nozzle_size_CP4 defines the specific nozzle diameter when a
specific nozzle size should be used. In this case, the data in
Nozzle_size_max. is not used; the FCP IV-3 is forced to use the
specified nozzle diameter to place the part. Do not input
Nozzle_size_CP4 if automatic selection of the nozzle is desired.
