● Fastening Curves (Waveforms) (Storage for Respective Spindles)
Fastening Curve files are stored in the automatically-generated folder “CURVE.” Inside the “CURVE”
folder, folders each with a name expressing the year and month, such as “201309,” are generated
automatically, and a folder is automatically generated in the manner of “201310,” “201311,” “201312,”
etc..
Inside the “201309” folder, folders each with a name expressing the year, month, and day, such as
“20130901,” are generated automatically, and a folder is automatically generated in the manner of
“20130902,” “20130903,” “20130904,” etc..
Inside the “20130901” folder, folders each with its name being the time of the fastening curve storage
that is saved first, are generated automatically in the manner of “123456~,” “123616~,” etc.,
As an example, inside the “123456~” folder, the following file is stored at the end of the fastening
operation.
CURVE¥YYYYMM¥YYYYMMDD¥hhmmss~¥YYYYMMDD_hhmmss.nracd (nracd format)
Year/Month
40 sets of fastening waveforms are stored in each file. When 40 sets of fastening waveforms have
been stored, the next file is generated automatically inside the “20130901” folder.
Also besides the fastening waveforms, “index.txt” for folder identification is generated inside
“CURVE.” The contents of index.txt are erased each time a folder is generated automatically.
