Intended Design — Digital Model — Selected Tool — CAM Parameters — Estimate Time (€€€!)
The exercise attempts to exploit CAM parameters for generating texture on the given surface. Following are the values for milling with a 26mm diameter, round nose milling tool, required for the desired effect.
THE HITCH
The experimental flip of the processes, (Parallel cut preceding the Rough cut instead of vice versa) proves erroneous. Besides other problems as follows:
The experimental flip of the processes, (Parallel cut preceding the Rough cut instead of vice versa) proves erroneous. Besides other problems as follows:
- Issue 1: The milling machine’s belts (controlling Y-direction movement) slip over the sprocket due to a broken rubber tooth.
- Result 1: Unequal thickness of ridges (and valleys), some as thin as 1 mm
- Issue 2: Usually the horizontal cut is step 1, followed by parallel finish. The sequence was flipped.
- Result 2: The thin ridges were severed violently during stage 2 as the tool attempted to mill horizontal rough cut.
SOLUTION
Milling stalled twice. The process which was supposed to take 20 minutes took an hour both due to technical and design problems. A parallel horizontal cut is proposed to save the texture on the surface and is executed perfectly.
