7. INFEED MACHINING IN C–AXIS
FACE MILLING PROCESS
C–AXIS FAPT FUNCTION
493
Machining type
Select CAXIS F. MILL process from the machining definition
screen.
Tool data
Use an end mill tool for milling.
Cutting conditions
The DRIVE ...DR= prompt is displayed on the cutting condition
screen before the prompt for the machining method. To perform
in–feed machining, define 1. Otherwise, define 0.
When a cutting condition is newly defined, initial values are defined.
When a family program that has been created using an earlier version
is loaded, 0 is defined.
Select and define one of the following three types of in–feed
machining methods.
DRIVE...DR = (1: on 0: off)
In–feed machining methods ... TP =
Select one of the following machining types. (initial value: 2)
1: Roughing
2: Finishing
3: Roughing finishing
If infeed machining is defined, the following prompts are displayed.
Define a value for each prompt.
Cutting allowance ... RX = Cutting allowance in the X axis direction
(initial value: undefined)
RZ = Cutting allowance in the Z axis direction
(initial value: undefined)
Cutting width ........... W1 = Depth of a single cut in the X axis direction
(initial value: tool diameter DT * value in
system parameter No. 372)
* If another cutting method is selected, the
initial value is resumed.
Cutting depth ........... D1 = Depth of a single cut in the Z axis direction
(initial value: undefined)
Finishing allowance ... TX = Finishing allowance in the X axis direction
(initial value: value in system parameter
No. 368)
TZ = Finishing allowance in the Z axis direction
(initial value: value in system parameter
No. 373)
Note the following when defining data for cutting conditions:
(1)If multiple face millings are defined upon figure definition, or if
cutting on the entity of a face milling is defined, infeed machining
cannot be defined.
If an attempt is made to make such definitions, an error occurs
(correct key input is required) and another input is not accepted.
(2)When infeed machining is performed with the method specified
by machining type 2 (finishing), the prompts for cutting allowance
(RZ) and cutting depth (D1) are not displayed.
(3)If an attempt is made to input a negative value in any of the prompts
for the cutting width (W1), number of cuts (N1), cutting depth
(D1), and finishing allowance (TX/TZ), an error occurs (correct
input is required) and another input is not accepted.
