You're machining entirely too fast for that machine. You are losing steps or the machine is deflecting. The part you show appears to be less than 4 or 5" wide. There isn't enough room for the tool to accel to 3 IPS and Decel to 0 IPS in that distance...that means you're not running at a properly set speed to start with. Furthermore, small tools NEED high RPM to at the very least get into the right chipload range. You should be running that 1/8" around 18,000 RPM and your MS somewhere in the 1.5 to 2 IPS range.
When quality sucks, slow down AND check your machine...but you should already be doing that regularly in addition to CLEANING the machine regularly...RIGHT? It needs more attention & maintenance than your other woodworking power equipment.
Question for EVERYONE: Have you ever seen a solid carbide tool deflect? I never have. Carbide is crystalline in composition and will SHATTER and snap off before it ever deflects. High Speed Steel (HSS) WILL deflect. Carbide = Nope. QUESTION #2: If the bit isn't deflecting, then what is? Follow the line of logic and find out what needs to be adjusted or if you are machining too fast.
Bonus - If you are using speeds straight out of the default tool database in the Vectric products, stop immediately. There was no logic behind the numbers that programmers put in there as sample data...you NEED to pick the right speeds for the work YOU are doing.
