PURPOSE:To ensure a quick calculation of the designed external secant or the like for a line shaping arithmetic device, by using an arithmetic means having a condition under which the total sum is equal between the field external secant and the designed external secant and the sum of differential moments of the final terminal or the total sum difference between the inner and outer work shifting extent is set at ''0''. CONSTITUTION:The measurement data at plural points of measurement within a shaping section of conventional line is supplied to the storage part 8 from the input part 7. The conditional data is calculated at the arithmetic part 9a to secur at equal value between the total sum of the field external secant and that of the designed external secant; the conditional data is calculated at the arithmetic part 9b to secure the sum of ''0'' for the differential moment between the field and designed external secants across the final point of shaping section; and the conditional data is calculated at the arithmetic part 9c to obtain the difference of ''0'' for the absolute value difference of total sums between the inner and outer work shift degrees. The designed external secant is calculated at the designed external secant arithmetic part 10 and from said conditional data, and the work shifting extent is calculated at the shifting extent arithmetic part 11 from the designed and field external secant to be displayed at the output display part 12. In such way, a quick and accurate calculation is possible for both desiged external secants and the work shifting extent. |
