SAFETY PRECAUTIONS

GENERAL WARNINGS

WARNING

1.

Before operating the machine, thoroughly check the entered data on the screen. Operating the
machine with incorrect data may result in the tool colliding with the workpiece and/or machine,
possibly causing damage to the machine and/or tool itself, or injury to the user.

2.

When the tool offset function is used, before activating the machine, check the direction and
value of the offset to ensure that the tool will not collide with the workpiece or machine. Any
collision may cause damage to the tool and/or machine, or injury to the user.

3.

Before starting the NC program prepared using the conversational function, thoroughly check
the contents of the NC data to ensure that the tool path and machining processes are set correctly ,
and that the tool will not collide with the workpiece or machine (including the chuck and
tailstock). Before starting a production run, perform a dry run to ensure that the tool will not
collide with the workpiece or machine (including the chuck and tailstock). For example, start
the machining program without mounting a workpiece on the machine. Any collision may cause
damage to the tool and/or machine, or injury to the user.

4.

Before using the conversational function to prepare a machining program, determine whether
the tool data, material data, setting data, system parameters, and MTF data are set as specified
by the machine tool builder. If these data values are not set appropriately, the cutting conditions
necessary for machining may not be set properly , possibly causing damage to the tool, or injury
to the user.

This manual is for conversational automatic programming function.
The conversational automatic programming function II is software in
which functions of an epoch–making automatic programming system
“Symbolic F APT” are assembled, and this “Symbolic F APT” allows even
unexperienced NC programmers to produce NC data for machining at
once simply by depressing buttons according to the instructions on the
graphic display CRT. The CNC can execute machining according to a
program soon after programming it at a site, or it can execute another
programming during machining.
The Symbolic FAPT produces NC data and loads them into built–in
memory (machining memory). Machining is made according to the NC
data in memory (also called NC program).
During machining, another program can also be produced by using
Symbolic FAPT function. When the machining memory has been
unloaded after machining, another program being prepared at the
automatic programming section is registered to the machining memory.
Since NC data loaded in machining memory are prepared in standard NC
language, an operator who knows the standard NC language can directly
check or modify NC data of standard NC language in machining memory
by using the CRT.
(Since NC data can be registered again to machining memory after
modifying NC data at the automatic programming section without any
need of modifying machining memory data, it is not necessary to modify
machining memory data usually.)

CONVERSATIONAL AUTOMATIC PROGRAMMING FUNCTION

(1)The NC data thus produced automatically by Symbolic F APT are not

directly used for machining, but they are once loaded to the machining
memory .

(2) The automatic programming unit is not capable of storing various

information of machine tools and machine control unit.
Note that control information of machine tools can be processed only
in machine control unit.

(3)The machining information can be input to CNC by the following two

methods.
(a) Method of loading automatic programming results into the

machining memory after automatic programming has been made
by using the Symbolic F APT. This is a standard method, which can
be used without any knowledge on NC tape format.

(b)Method of inputting the machining information into the machining

memory of the machine control unit by MDI operation.
Since this operation is the same as in NC unit for ordinary MDI
input, you are requested to be familiar with NC tape format, etc.

(1)This manual does not cover the functions on the NC side.
(2)The function of an NC machine tool system does not depend only on

the NC, but on the combination of the machine tool, its magnetic
cabinet, servo system, the NC, operator’s panels, etc. It is too difficult
to describe the function, programming, and operation in various
combinations of them. This manual generally describes them from the
standpoint of the NC. So, for a particular NC machine tool, refer to
the manual issued by the machine tool builder, which should take
precedence over this manual.

(3) Notes refer to detailed and specific items. So, when a note will be

encountered, terms used in it sometimes will not have been explained
it. In such a case, first skip the note, then return to it after having read
the manual in outline for details.

(4) For 16–T CAP II, the manual covers only the 5710 system and the

5800 system series and later. The earlier series may not support some

OPERATION BY SYMBOLIC FAPT

SYMBOLIC FAPT

The Symbolic FAPT is an epoch making NC automatic programming
system which enables even unexperienced NC operators to prepare NC
tape immediately according to the instructions on the graphic display
CRT.
Each process from design drawings to NC tape preparation is entirely
advanced by the conversational operation with the graphic display CR T.
For (1) selection of coordinate system by drawing methods (2) selection
of figures of blank and input of dimensions (3) input of parts figures and
dimensions, and (4) selection of machining process and decision or
cutting conditions etc., the operator has only to answer questions from the
CR T.
The parts figure can be input simply by depressing corresponding symbol
keys on the operator’s panel according to the profiles of a workpiece
described on design drawings.
When dimensions and various data are input, various pieces of reference
information are illustrated on the CRT from time to time, and questions
are given to the operator using daily language.
When data are input, the figure of blank and parts profile are drawn
immediately , and automatic calculations of NC command data are started.
The tool path is concurrently displayed as figures.
Unless otherwise specified, this manual uses the screens of the 15–TFB
or 16–T CAP II to describe functions.

Batch Input Functions for Chamfering and Corner R

(1)Chamfering

Normally, it is customary practice to chamfer a corner unless
otherwise specified for the machined parts in the drawing. Unlike the
specified chamfer, this chamfering is not described in the drawing, the
chamfering amount is constant and many in most cases.
Consequently, when the machined figure is prepared, it may be
troublesome to enter many chamfering elements. This function inputs
a given amount of chamfer exclusively to all corners to which no
chamfer (element symbol C) is input yet after all machined figures are
completely entered.

After the machined figure for turning is entered, the following screen
is displayed.

Function for Defining the Center of an Arc According to a Given Single Coordinate

In part figure definition, the system can define the center of an arc even
if only one of the coordinates (X or Z) is given. This feature eliminates
the need for manual calculation.

2) Defining a figure (entering a part figure)
The four points of the figure are defined in the following order: A

(start point), B, C, and D (end point).
The figure can be defined only by entering the following data in the
command specifying the arc from point A to C.

Figure element 1) SR = 2

SDX = 20
SZ = 0
PE = 1

DX = jjj R = 26
Z=jjj CDX = jjj
TL = jjj CZ = 18
TN = jjj

After the data is entered, the system can calculate the center of the arc.
The system prompts the operator to select a desired center.
On the screen, calculated centers are automatically scaled and

indicated by graphic cursors.
The system temporarily scales the centers so that the operator can

easily select one of the centers. After the operator specifies the desired
center, the original scale is restored.

Selecting a center PC = j (³: Right, ²: Left, ´: Up, ±: Down). .
The desired center is the intersection of auxiliary circle A (center (20,

0) and radius (R) 26) and the straight line of Z = 18. Since the circle

and line intersect at two points (PC1 and PC2), the operator must
specify either of them. (See the figure below.)

TL = jj1CZ=jjj
TN = jj1

Figure element 3) DX = 70 R = 15

TN = jjj CZ = 33

As two end points are possible (PE1 and PE2), the operator must specify
either of them. (See Fig.3.2.8.)

On the screen, calculated end points are automatically scaled and
indicated by graphic cursors.

The system temporarily scales the two end points so that the operator can
easily select one of them. After the operator specifies a desired end point,

WARNING

No check of the validity of a machining sequence is made.
Therefore, even when a machining sequence specified in
the machining definition includes any invalid process steps
(inner surface machining without drilling, or finishing before
roughing, for example), the entire machining sequence is
reflected on the prepared NC data. When defining
machining, check the specified machining sequence.
Failure to specify a valid machining sequence may result in
the tool colliding with the workpiece and/or machine, or
forced machining occurring, possibly causing damage to
the machine and/or tool itself, or injury to the user.

When the machining definition soft key (No.4) is pressed on the

initial screen, the following screen appears. On this screen, the manual
machining definition item and the automatic process determination
function can be selected.
