Vito's verbose slide rule

German Machining?

Front Back

Data:

  • Double circular + linear slide rule in each side.
  • Lot of text.
  • “Rationalisierungsinstitut Deutinger”

Question:

  1. Is it for mechanical machining?
  2. Manufacturer?
    Is this the Universal-Kalkulationsuhr UKM-8 sold (for 145 DM!) by Rationalisierungsinstitut J. Deutinger, Lauterbach bei Rosenheim? Industrie-Anzeiger, Vol.90 Nr.71-87 (1968) page 69 Andries de Man
     It calculates production times for various machining techniques. Typically used by a production planner. Karl Kleine
     Fearns made a similar circular slide rule. David Nichols
     In the end, it is used for cost estimation. Alistair Pearson
     The Rationalisierungsinstitut J. Deutinger slide rule is described on pages 235–238 of Klaus Greis, “Betriebsrechenschieber 1. Teil” Eamonn Gormley, Andreas Faßbender
     IMO the double circle represents the contents of a standard Machinist's handbook data. George W. Anderson
