VARIOUS FUNCTIONS AND
PRECAUTIONS OF Symbolic FAPT
When a system parameter value or an MTF parameter
value is modified, check the prepared NC data. Machining
with incorrect NC data 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.
The functions for preparing NC tape for chaser lathe are provided. The
major functions are as follows.
1) It is no longer necessary to define the tool by reversing it, if the tool
is at the rear side.
2) The tool can be replaced by drawing the Z axis only to the specified
position. The above functions will be detailed below.
(1)Setting of parameters
Set the following MTF parameters
No.1051 (Turret position) Set whether the standard tool is. . . . . .
positioned on this side or on the
No.1055 (Turret type) = 1
No.1084 (Moving sequence of simultaneous one axis)
Set the moving sequence of return. . . . . .
relief and approach.
No.1105 (Number of digits of T code and offset number)
Set 0 if T code is not divided into. . . . . .
tool number and offset number.
Others, the MTF and system parameter is set according to the needs.
(2)Specifications of index position
The X value is not specified, but the Z axis only is specified at the index
position. The tool can be retracted only in Z axis at tool change, by
(3)Setting of tool data
The specification method of data differs according to whether 1 or 2
is specified or 3 or 4 is specified as the drawing format. This concept
is the same as in ordinary turret lathes.
(i) When 1 or 2 is specified;
The drawing format is the same as in the case that the opposite side
is specified as +X. This will be explained, referring to the outer
diameter cutting, as an example.
