内容記述(抄録等)
The main purpose of this investigation was to search out a suitable swaging condittion of band-saw tooth, by comparing the relations between the standard deviation of swage spread(kerf width) and the mechanical vibration level of band-saw sharpner.
Vibration level of grinding axis were measured by useing the following aparatus, and frequency c/s and amplitude mm were calculated from the recording waves.
Accelero-meters. (capacity ±2g, ±5g)
Dynamic strain amplifier.
Electro magnetic oscillograph.
The position of accelero-meter adheared are shown in photo 1~3.
Results of our test for each sharpener in six factories are shown in Table 4, and Fig. 4 and main values of vibration level and standard deviations(δ) of setting spread are as follows,
Amplitude 8~389×10^<-4>mm
Firequency 13~77c/s
δ of shaping condition 6.7~1.7 x 10^<-2>mm
δ of sharpening condition 5.9~2.4 x 10^<-2>mm
From these results, it was reduced that the final standard deviation of setting spread (kerf width) formed by sharpener would be determined by either δ of shaper condition for the tooth point or vibration level(V) of grinding axis, and the authers determind a next experimental formular for relation between δ and V. (Fig. 6)
δ mm = 0.8 V+0.02 mm
In this case,
δ : final standard deviation of kerf width
V = √<a^2_⊥ + a^2_//> a is amplitude (mm) of grinding axis
