Function Explanation
High-speed cycle
machining (G05)
(Example)
Cycle 1: connection 2, repetition 1
Cycle 2: connection 3, repetition 3
Cycle 3: connection 0, repetition 1
G05P10001L2;
Cycle is executed as 1, 2, 2, 2, 3, 1, 2, 2, 2, 3
High-speed remote
buffer A (G05)
Specify G05 only in a block using normal NC com-
mand format. Then specify move data in the special
format shown below. When zero is specified as the
travel distance along all axes, normal NC command
format can be used again for subsequent command
specification.
High-speed remote
buffer B
(G05)
High-speed remote buffer A uses binary data. On the
other hand, high-speed remote buffer B can directly
use NC language coded with equipment such as an
automatic programming unit to perform high-speed
machining.
High-precision contour
control
(G05)
Some machining errors are due to the CNC. Such
errors include machining errors caused by accelera-
tion/deceleration after interpolation. To eliminate
these errors, the following functions are performed at
high speed by an RISC processor. These functions
are called high-precision contour control functions.
(1) Function for multiple-block look-ahead accelera-
tion/deceleration before interpolation. This func-
tion eliminates machining errors due to accelera-
tion/deceleration.
(2) Automatic speed control function which enables
smooth acceleration/deceleration by considering
changes in the figure and speed and allowable
acceleration for the machine. This is performed
by reading multiple blocks in advance.
