9.2 Digitizing with TS 120
Digitizing is possible with all HEIDENHAIN triggering touch probes. However, because the digitizing
process can take several hours to complete, it is advisable to use the TS 120 touch probe with signal
transmission by cable. The TS 511 touch probe with its infrared signal transmission can be
continuously operated for up to 8 hours on one battery charge.
Technical Requirements
- "Digitizing with TS 120" is possible with TNC 360 using software types 259 90x03 (TNC 360) and
260 02x 04 (TNC 360 C) See also Chapter "Introduction", Section "Software".
- Installing the software module "Digitizing with the TS 120". The ID number of the logic unit
indicates whether the software module is already installed (see Chapter "Introduction", Sections
"EPROM locations", and in Chapter "Mounting and electrical installation", Section "Hardware
components"). If the module is already installed, the software number of the option will appear
beneath the NC and PLC software number, when the system is switched on or when the MOD
key is pressed.
- Interfaced touch probe TS 120.
- The machine must be optimized for "Servo lag operation".
The digitizing sequence is optimized by the machine parameters.
Machine parameter MP6210 is the value for the oscillations executed by the touch probe as it scans
the form. It is governed by the dynamic response of the machine. The dynamic response is in turn
determined by the Kv factor (servo lag operation). The greater the Kv factor, the greater the number
of oscillations.
Machine parameter MP6210 determines the maximum probing feed rate in conjunction with the
programmed probe point interval, P.P.INT from the scanning cycles "Meander" and "Contour Lines":
F [mm/min] = PP.INT [mm] x oscillations [1/s] x 60 [s/min]
This relation gives the formula for calculating the input value of MP6210:
Oscillations [1/s] =
1)
optimized F [mm/min]1)
PP.INT [mm] x 60 [s/min]
The optimized probing feed rate depends on the feed rate in the normal direction (MP6230).
