Threshold for the travel ratio between the tool tip point and machine end point for time study
Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
What it does
Threshold for the travel ratio between the tool tip point and machine end point for time study
During the tool center point control (G43.4, G43.5), the feedrate used for calculating the deceleration time at corners is switched from the feedrate at the machine end point to that at the tool tip point if the travel ratio between the tool tip point and machine end point (travel at the machine end point/travel at the tool tip point) exceeds the value set for F242. When 0 is set, 5 is assumed. When a value beyond 20 is set, 20 is assumed.
