English to Swedish Tech/Engineering Engineering (general)

The context has to do with a gear inspection machine/software that measures gears (kugghjul).

Examples:

"Based on the helix  hand and flank selected, the Z height is automatically adjusted to compensate for Z movement."

"For example, you may be asked to select the geometry for certain part types, or the hand of a helix part, and so on."

I found this definition on a site:
"Helix Hand – the direction of the helix angle expressed as either right or left. Looking down the central axis of the gear, a right hand helix angles from left to right down the tooth face away from you. The opposite is true for a left hand helix."
