CNC Machinist First Shift

About the role

CNC Machinist maximizes efficiency through the operation process and observes multiple HAAS CNC Lathes that use single or multiple spindles with automatic indexing and feeding mechanisms to machine metal bar stock for the manufacture of various types of aerospace products. Processes methods in accordance with product specifications and quality standards.

Responsibilities

• Understand programming requirements for Siemens, Sinumerik and Fanuc controls.
• Write programming codes using MASTERCAM based on the blueprint for the manufacture of aerospace products.
• Make necessary corrections to programs.
• Be familiar with ID and OD threading and all tooling associated with the operation.
• Calculate and set controls to regulate machining factors such as speed and feed.
• Observe operation is to specification on CNC machine to produce various types of aerospace products.
• Stop machines to remove finished work pieces, or to change tooling, setup, or work piece placement, according to required machining sequences.
• Detect malfunctions or out-of-tolerance machining, and adjusts machine controls or control media as required.
• Measure dimensions of finished work pieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures.
• Remove and replace dull cutting tools.
• Perform preventive maintenance.
• Mount, install, align, and secure tools, attachments, fixtures, and work pieces on machines, using hand tools and precision measuring instruments.
• Adjust machine feed and speed, change cutting tools, or adjust machine controls when automatic programming is faulty or if machines malfunction.
• Lift work pieces to machines manually or with the use of hand tools.
• Modify cutting programs to account for problems encountered during operation and save modified programs.
• Calculate machine speed and feed ratios, and the size and position of cuts.
• Prepare and verify production machine operations on trial run to ensure accuracy of machine settings.
• Insert control instructions into machine control units to start operation.
• Recognize improper machine functioning and recognize defects in machinery, measuring instruments or equipment.
• Notify or inform lead or immediate supervisor when machine maintenance is needed.
• Perform Statistical Process Control (SPC) checks per specification, Mastercam (CAM software) and act in accordance with output and demonstrate knowledge.
• Read & study blueprints, sketches, drawings, manuals, specifications, or sample part to determine dimensions and tolerances of finished work-piece, sequence of operations, and setup requirements.

Skills

• Able to read, comprehend, and execute directions from mechanical drawings.
• Able to measure dimensions of products to verify conformance to specifications, using measuring instruments such as rulers, calipers, gauges, or micrometers.
