Cold Saw/V1 Design Rationale

Conceptual Parameters

• Baseplate

• 2 Fixed Blocks (mounted to baseplate by XXX, 2 shaft holes, 1 threaded rod hole)

• 1 Moving Nut Block (rides on 2 shafts, driven by a threaded rod that moves a nut welded to the block)

• 2 Shafts (radially held on the Fixed Blocks, axially held by 2 shaft couplings on the outsides of the Fixed Blocks)

• 1 Threaded Rod (radially held on the Fixed Blocks, axially held by 2 shaft couplings on the outsides of the Fixed Blocks, drives a nut welded to the Moving Block)

• 1 Clamp Handle (welded to the Threaded Rod)

Clamp Threaded Rod and Shafts Positioning

• The initial design branch split is whether the mount holes for the Shafts and Threaded Rod are propagated along a common centerline or not.

• Common centerline positioning provides the highest possible power transfer that can be attained through the 2 shaft 1 threaded rod system- because disjointed positioning can cause friction and bend-related force vectors not along the clamping axis of motion.

However, because the workpiece must be clamped above the centerline clamp system, bending can still occur.
