Axis substitution is used on machines that allow simultaneous four-axis movements.

option,the part will be rotated about the rotating axis while the tool moves perpendicular

size of the cylinder that the toolpath is rotating about.

Chain the contours from which the toolpath is to be generated.

Mastercam displays the Toolpath parameters tab, where you can select a tool.

If you are creating a 5-axis rolled toolpath and the part is not already rolled, select Rotary axis. In the Rotary axis dialog box, select Axis substitution. Set the diameter, rotation direction, and which axis is to be replaced.

Select the Contour parameters tab and enter your cutting parameters.

Set Depth to a negative amount and choose Incremental. This sets the depth of the tool tip. If you use a tapered tool, the toolpath will be offset so that the edge of the tapered tool runs on the wrapped or flat chain, resulting in the depth that you have entered.

Show Taper  锥度显示

Show Taper If you are using a tapered tool, tell Mastercam how you want to represent the taper. Select Lines to show a red line at each tool vector from the tip of the tool to the point on the rolled chain that the tool vector was generated from, giving a line along the

3-Axis Tool Path 生成3轴刀路

3-Axis Tool Path Select this option to produce a 3 axis toolpath. This is useful when a taper tool is used to run up and down the crease on inside sharp corners.

Prerolled  包覆

Prerolled Use the Prerolled options to tell Mastercam whether or not the geometry is flat or already rolled. Select No when the chained contours are flat, or select About X or About Y to indicate the axis around which the chained entities are rolled.

Z=Radius  自动设深度

Z=Radius Flat entities at Z = 0.0 will roll around the chosen axis at the diameter that you enter in the Rotary axis dialog box. If the entities are at a positive Z height, select Z = Radius to automatically set their rolled radius equal to their Z height.

Auto Reverse  串联自动换向

Auto Reverse Select Auto reverse to use an open chain as the centerline of a slot or blade.  The toolpath will be generated in the selected chain direction, around the end, back down the other side, and around the start.

Slot 铣槽和槽宽设置

Select Slot and enter a Slot width to use the chained contour as the centerline of a slot.  Mastercam offsets the tool from the centerline to produce a slot of the given width around the chained contour.  If you enter a Stock to leave amount, the leftover stock will be on the slot wall and towards the chained contour.

嗯嗯...可以看到圖片了

請問工作上有用Rolldie的朋友.....Rolldie能自由加上進退刀嗎 ??

用于不指向回转中心的侧壁外形铣，可以进退刀。
