Constant Cutting Rate (G96/G961/G962, G97/G971/G972, G973, Lims, Scc) - Siemens SINUMERIK 828D Programming Manual

6.3 Constant cutting rate (G96/G961/G962, G97/G971/G972, G973,
LIMS, SCC)
Function
When the "Constant cutting rate" function is active, the spindle speed is modified as a
function of the respective workpiece diameter so that the cutting rate S in m/min or ft/min
remains constant at the tool edge.
This results in the following advantages:
● Uniformity and consequently improved surface quality of turned parts
● Machining process is kinder to tools
