Micropolishing Parameters
Pre-Process:
- Workpiece - Surface finish.
- Workpiece – Geometry (size, taper, barrel, hour glass, roundness, lobing)
- Workpiece - Material
- Workpiece - Hardness
- Workpiece - Surface cleanness (before process and measurement). (oil, lint, coating, etc.)
- Workpiece - Temperature
- Type of measuring device-
- Brand and model of measuring device
- Measurement parameters – Ra, Rpk, Tp. etc.
- Tp checked at (fill in dimension) depth
- Measuring instrument tip – stylist (point or radius)
- Stylus tip angle
- Stylus tip radius dimension
- Stylus force
- Filter type
- Cut – off length
- Assessment length
- Mastering (certification)
- Environment – gauging
|
Machine:
- Workpiece - Surface finish
- Electrical supply
- Proper set up -
- Proper oscillation detail
- Proper tooling – shoes, guides, rollers, abrasive tape
- Proper workpiece headstock driver
<
- Proper tailstock setting
- Proper program
|
Process:- Abrasive tape manufacturer
- Abrasive tape micron size (grit)
- Abrasive tape mineral (aluminum oxide).
- Abrasive tape backing (Q-back)
- Abrasive tape index frequency
- Abrasive tape length of index
- Coolant type
- Coolant filtration (10 micron)
- Coolant cleanness
- Coolant – method of application
- Surface feet of Micropolishing – clockwise (time, rpm, revolutions, diameter)
- Surface feet of Micropolishing – counterclockwise (time, rpm, revolutions, diameter)
- Final direction of revolution (CW or CCW)
- Pressure
- Oscillation frequency (angle of crosshatch)
- Oscillation distance
- No oscillation
- Lead – LH, RH – no lead
- Tooling type – backup shoe:
- Material
- Hardness
- Configuration – “V”, bored, other
- Solid mounting
- Pivot mounting
- Double pivot mounting
|
Post Process:
- Surface cleanness
- Temperature
- Type of measuring device
- Brand and model of measuring device
- Measurement parameters – Ra, Rpk, Tp, other
- Measuring instrument contact tip – stylist (point, radius)
- Mastering (certification)
