Zorluk: OrtaStationary Power Saws

A woodshop technician needs to make clean, splinter-free crosscuts across the grain of hardwood boards using a stationary compound miter saw. Which saw blade specification is best suited for this operation?

  1. A
    A blade with a low tooth count and deep gullets designed to clear long wood fibers
  2. A blade with a high tooth count and alternate top bevel teeth designed to shear wood fibers cleanlyCevap
  3. C
    A steel blade adjusted with extreme tooth projection to maximize cutting friction against the wood grain
  4. D
    A high-speed friction disc designed to burn through material at high drill press spindle speeds

Cevap

A blade with a high tooth count and alternate top bevel teeth designed to shear wood fibers cleanly
Crosscutting requires knife-like cutting action to sever wood fibers without tearing the underside or face of the board. A high tooth count combined with alternate top bevel (ATB) teeth cleanly shears through the grain, delivering a smooth, tearout-free finish on a stationary miter saw.

Adım Adım Çözüm

1
Identify the cutting orientation relative to the lumber grain
The operation is crosscutting (cutting perpendicular to the wood grain).
Cutting across grain requires slicing fibers rather than chiseling them along their length.
2
Select the proper tooth count and bevel grind for crosscutting
A high tooth count blade with Alternate Top Bevel (ATB) geometry is required.
Higher tooth counts take smaller individual bites and knife-like ATB teeth cleanly shear cross-grain fibers without splintering.
