depth.

Select the 1.0 Flat end mill using the Filteroptions as shown in the facing operation.

Make the necessary changes to match the parameters with the screenshot to the right.

Remember that theFeed rate. Plunge rate, Retract rateand Spindle speedvalues are all define in the

parameters of the tool definition. Change them as needed.

Page 741


47/77


Select the Pocket parameterspage and change the parameters as shown.

Depthvalue sets the final machining depth for the pocket operation. The value is set to 0and

incrementaland is measured from the two geometry chains that we selected. This insures that

both of them are going to be machined to the appropriate depth.

Choosing Incrementaltells the system to calculate the value relative to either the current top ofstock (as with Clearanceparameter), relative to the selected geometry (as withTopof stockand

Depthparameters), or relative to the depth of each cut (as with Feed planeand Retract).

XY stock to leaveallows you to set the amount of stock in XY plane (along the pocket walls) that

will be machined in a separate finish operation.

Z stock to leaveallows you to set the amount of stock in Z (at the bottom of the pocket) that will

be machined in a separate finish operation.

Page 742


48/77


Enable Depth cuts and change the parameters as shown.

Depth cutsare the Z axis cuts that the toolmakes in a pocket toolpath.

Max rough step sets the maximum

amount that can be machined in one step.

By pocketenable the system to complete

all depth cuts in the first pocket before

moving to next one.

Mastercam never performs unequal depth cuts. For example, in our case, the left side pocket is 0.375

deep; the step is calculated: (0.3750.02)/2 = 0.1775 which is smaller then 0.3. The same way the system

calculates the step for the second pocket; (0.750.02)/3 =0.2433

Select the Roughing/Finishing parameterstab.

Page 747


53/77


STEP 16: REMACHINING THE TWO POCKETS.

Note that the 3/4 Flat End Mill could not clean the 0.125 radius fillets. Using the 1/8 Flat End Mill to

remove all the material inside the pocket will not be efficient. We will remove the remaining material only

by using a 1/8 Flat End Mill tool with the remachining pocket style.

Toolpath Preview:

16.1 Copy the existing last pocket operation

You can copy an operation only when machining the same geometry using the same toolpath. Advantages

of using a copy of an existing operation is that we dont need to select the geometry chains and we can

use some of the parameters set up in the original operation.

Select only the second Pocket (operation 4).

Rightmouse clickand hold it down on the folder icon in front of the second Pocket toolpath.

Drag the mouse down and release it.
