Groove roughing method

 

Faces that make up the model to mill are cut into vertical planes, parallel to the XY plane and to each other, to take into account the tool corner radius value and the stock to leave. These planes are regularly spaced at a value equal to the milling pitch (pass depth).

 

The following milling types are available:

 

Plunge

 

The tool completes a series of successive parallel plunges, spaced according to the pitch value, starting with the stock profile and ending with the finished profile. Each plunge is interrupted based on the pass depth. At each interruption, the tool goes back up the value of the safety distance to break the chip. A delay is enabled at the bottom of the plunge.

B: Successive Plunges

 

One-directional Step

 

The volume of initial material to remove has been precut perpendicularly to the tool axis into several basic volumes based on the pass depth value. Each basic volume or step is then roughed according to the first method. All basic volumes are milled by following the "starting element direction to the ending element direction".

C: One-directional Mode Step Plunge

Bidirectional Step

 

The volume of initial material to remove has been precut perpendicularly to the tool axis into several basic volumes based on the pass depth value. Each basic volume or step is then roughed according to the first method. All basic volumes are milled by alternating the "starting/ending item direction".

One-directional Square

 

The tool plunges until it reaches the value of the pass depth, then cylinders the part using the right or left flank. The operation is repeated until a finished product is achieved. In One-directional mode, cylindering is only completed in one direction.

 

 

A: Depth Value

B: Square Cycle in One-directional Mode

Bidirectional Square

 

The tool plunges until it reaches the value of the pass depth, then cylinders the part using the right or left flank. The operation is repeated until a finished product is achieved. In Bidirectional mode, cylindering is completed by alternating between the start item and the end item.

 

 

A: Depth Value

B: Square Cycle in Bidirectional Mode

Zigzag

 

The tool required for this operation must allow plunging and cutting on the left and right flanks. The volume of material to remove has been precut perpendicularly to the tool axis into several basic volumes based on the pass depth value. The basic volumes are then transversally removed by alternative cutting.

 

 

A: Depth Value

B: Zigzag Mode

Alternate

 

The volume of initial material to remove has been precut perpendicularly to the tool axis into several basic volumes based on the pass depth value. Each basic volume or step is then roughed according to the first method. The plunged is set using the "First Plunge" setting

 

 

A: Depth Value

B: Alternate Mode

Trochoidal

 

The tool plunges until it reaches the value of the pass depth, then cylinders the part using the right or left flank. The operation is repeated until a finished product is achieved. In Bidirectional mode, cylindering is completed by alternating between the start item and the end item.
