Structure:

ENTRY: (required) NXentry

@version: (required) NX_CHAR

Version specifier of this application definition.

definition: (required) NX_CHAR

Official NeXus NXDL schema with which this file was written.

Obligatory value: NXlab_electro_chemo_mechanical_preparation

workflow_step_identifier: (required) NX_UINT

workflow_step_description: (required) NX_CHAR

SAMPLE: (required) NXsample

USER: (required) NXuser

grinding_machine: (required) NXfabrication

vendor: (required) NX_CHAR

model: (required) NX_CHAR

identifier: (recommended) NX_CHAR

GRINDING_STEP: (required) NXprocess

A preparation step performed by a human or a robot/automated system.

sequence_index: (required) NX_POSINT

start_time: (required) NX_DATE_TIME

end_time: (required) NX_DATE_TIME

abrasive_medium_carrier: (required) NX_CHAR

Carrier/plate used on which the abrasive/(lubricant) mixture was applied.

abrasive_medium: (required) NX_CHAR

Medium on the abrasive_medium_carrier (cloth or grinding plate) whereby material is abrasively weared.

lubricant: (required) NX_CHAR

Lubricant

rotation_control: (required) NX_CHAR

Qualitative statement how the revelation of the machine was configured. If the rotation was controlled manually, e.g. by turning knobs choose manual and estimate the nominal average rotation. If the rotation was controlled via choosing from a fixed set of options offered by the machine choose fixed and specify the nominal rotation. If programmed use rotation_history (e.g. for automated/robot systems).

Any of these values: undefined | manual | fixed | programmed

force_control: (required) NX_CHAR

Qualitative statement how the (piston) force with which the sample was pressed into/against the abrasive medium was controlled if at all. If the force was controlled manually e.g. by turning knobs choose manual and estimate nominal average force. If the force was controlled via choosing from a fixed set of options offered by the machine choose fixed and specify the nominal force. If programmed use force_history (e.g. for automated/robot systems).

Any of these values: undefined | manual | fixed | programmed

time_control: (required) NX_CHAR

Qualitative statement for how long (assuming regular uninterrupted) preparation at the specified conditions the preparation step was applied.

Any of these values: undefined | manual | fixed | programmed

rotation: (required) NX_NUMBER {units=NX_FREQUENCY}

Turns per unit time.

force: (required) NX_NUMBER {units=NX_ANY}

Force exerted on the sample to press it into the abrasive.

time: (required) NX_NUMBER {units=NX_TIME}

Seconds

removal: (required) NX_CHAR

Qualitative statement how the material removal was characterized.

Any of these values: undefined | estimated | measured

thickness_reduction: (required) NX_NUMBER {units=NX_LENGTH}

How thick a layer was removed.

SENSOR_SCAN: (required) NXsensor_scan

CLEANING_STEP: (required) NXprocess

A preparation step performed by a human or a robot/automated system with the aim to remove residual abrasive medium from the specimen surface.

sequence_index: (required) NX_POSINT
