![]() I decided I should investigate what was going on. The other day I was single point fly cutting some tall plates with the Sieg X2 (no, I didn’t strip the plastic gears … yet) and noticed the column vibration was very significant. The reputation is such that Little Machine Shop has removed the Sieg’s tilting option on its mills in order to improve rigidity. In particular the tilting column variation of the X2 (the most common variation) has extreme chatter and vibration issues when trying to take anything more than very small depths of cut in steel. The Sieg X2 Mini Mill is know for the wet noodle characteristics of the column. Dr Yuen’s practical problem solving teaching is a refreshing and needed approach where many engineering students are ‘drowning’ in math and not able to solve real world problems. The analysis I did below was directly learned in his Machine Dynamics course as part of my degree in Manufacturing.
