What does spindle orientation mean?

Spindle orientation is when the spindle finds its home position just like a regular machine tool axis accept that its called orientation. Orientation is often needed to align the tools up properly in order to perform a tool change.

What is M19 in G code?

M19 adjusts the spindle to a fixed position. The orient spindle function allows P and R address codes. For example, M19 P270. orients the spindle to 270 degrees. The R value allows the programmer to specify up to two decimal places; for example, M19 R123.

What is backlash in CNC machine?

Backlash with a CNC is the same as taking a screw and threading a nut on to it. That small amount of movement between the threads is the cause of backlash. Since both the screw and nut threads don’t fit perfectly together there is always “Play”. This space between the gears is known as “backlash”.

What is mitotic spindle orientation?

Mitotic spindle orientation is essential for cell fate decisions, epithelial maintenance, and tissue morphogenesis. In most animal cell types, the dynein motor complex is anchored at the cell cortex and exerts pulling forces on astral microtubules to position the spindle.

What is the meaning of M-code?

M-code is the machine control language for CNC machining. It is used in combination with G-code to switch various machine functions off and on. This article will discuss M-code in general and how it applies to CNC machining.

What’s the difference between backlash and repeatability?

Repeatability and Backlash In measurements, repeatability is the ability of the measuring instrument to repeat the same results during the act of measurements for the same quantity. In mechanical engineering, backlash is a clearance or lost motion in a mechanism caused by gaps between the parts.

Why is the orientation of the mitotic spindle during mitosis is important for the fate of the daughter cells?

During mitosis, the mitotic spindle ensures the separation of the two genomes and positions the cytokinesis furrow, therefore coordinating karyokinesis and cytokinesis.

What is symmetric and asymmetric spindle?

asymmetric divisions. In polarized cells, orientation of the spindle perpendicular to the polarity axis causes a symmetric (proliferative) division (A). However, spindle orientation parallel to the polarity axis results in an asymmetric (differentiative) division (B).
