This function automatically specifies machining conditions when you
simply select a precision level that matches your machining purposes
when machining. The machining conditions are obtained based on the
selected precision level and two prescribed parameter groups
(precision–first and velocity–first).
The precision level can be selected from ten steps ranging from 1
(velocity–first) to 10 (precision–first).
It can be selected also on the screen or from the NC program.
NOTE
1 This is an optional function.
2 This function is usable only with APC, AI contour control,
and AI–APC.
3 This function is unusable on inch output machines (bit 0 of
parameter No. 1001 = 1).
This function consists of the following two screens.
(1)Machining parameter tuning screen
On this screen, the following parameters are set up for both velocity–
first (precision level 1) and precision–first (precision level 10) modes.
S Pre–interpolation acceleration/deceleration rate
S Bell–shaped acceleration/deceleration change time
S Allowable acceleration
S Post–interpolation acceleration/deceleration rate
S Corner feedrate difference
S Maximum allowable cutting feedrate
S Two items that can be set up at the user’s discretion
(2)Precision level select screen
On this screen, a precision level that matches your machining purposes
can be specified. Parameter values are calculated and displayed
according to the precision level corresponding to the velocity–first
parameter set (precision level 1) or the precision–first parameter set
(precision level 10), whichever is selected.
The precision level can be changed also using program commands.
NOTE
1 The bell–shaped acceleration change time is valid only if the
pre–interpolation bell–shaped acceleration/deceleration
option is available.
2 In APC, only the arc radius–based velocity clamp is
changed according to the allowable acceleration, because
no acceleration–based velocity determination function is
available.
