Horizontal lead/ramp
Lead distance in/out is the linear distance that a tool path extends beyond the ends of an open toolpath or toolpaths that are clipped against the stock profile. This parameter is specified as a percentage of the tool's diameter. If Lead Distance is set to 0.0, the toolpath starts or stops exactly at the ends of the profile.

Lead-in/out angle

Lead distance in/out
The Lead-in angle applies only over the Lead-in distance, so if the Lead-in distance is 0, the Lead-in angle has no effect.
The Lead-out angle applies only over the Lead-out distance, so if the Lead-out distance is 0, the Lead-out angle has no effect. The Lead-out angle is applied to the end of the finish pass for an open toolpath. It also applies to the last toolpath of a roughing pass if the Finish allowance is set to 0.
Ramp type — Select the stepover style from the list.
Ramp diameter — See Ramp type.
Minimum ramp distance — This attribute applies to the Finish operation. Enter the minimum horizontal distance for ramping. If the computed horizontal ramp distance is less than this, the tool plunges instead of ramping. Enter the value as a percentage of the tool's diameter.

Vertical ramp
Minimum Z ramp distance — This is the minimum vertical ramp distance allowed. If Minimum Z ramp distance is greater than the calculated ramp distance or Max ramp distance, the tool plunges.
Max. ramp angle — This controls the angle of the ramp.
Max. finish ramp angle — This is the same as Max. ramp angle, but for the finish pass.
Ramp from top — Disable this option to avoid ramping to depth on the Finish and Semi-finish pass of a 2.5D feature. This saves machining time.
This example shows the Finish operation for a Side feature.

Helical ramping — Enable this option to use helical ramping. Disable it to use zigzag ramping.
Helical Options — Click this button to open theHelical Ramp Options dialog.
Arc lead
Arc Lead — This changes the lead-in or lead-out move to be an arc. The endpoint of the arc is determined by the Lead distance and either the Lead-in angle or Lead-out angle.
